Problem 1: Detailed Solution

Okay, let's jump into the first problem. I'll write out the question first. Then give a detailed explanation of the solution. Let's pretend the problem is: "Calculate the total cost of a project given the following expenses: labor costs of $5000, material costs of $2000, and overhead costs of $1000." I'm using this as an example, but treat it like the real deal, and I'll show you how to approach it.

So, the problem is straightforward, but let’s break it down. First, identify what the problem is asking you to find. In this case, it’s the total cost of the project. Next, identify the given information: labor costs, material costs, and overhead costs. Finally, determine how to use the given information to find the answer. In this case, the total cost is simply the sum of all the individual costs. Here's the solution:

Total Cost = Labor Costs + Material Costs + Overhead Costs

Total Cost = $5000 + $2000 + $1000

Total Cost = $8000

Therefore, the total cost of the project is $8000. Now, let’s add some layers of complexity to this problem. What if the labor costs included a 10% bonus based on project performance? What if the material costs were subject to a 5% sales tax? What if the overhead costs included a fixed cost of $500 and a variable cost that was 2% of the labor and material costs? Let’s incorporate these additional factors into our calculation.

Revised Labor Costs = Original Labor Costs + Bonus

Bonus = 10% of Original Labor Costs = 0.10 * $5000 = $500

Revised Labor Costs = $5000 + $500 = $5500

Revised Material Costs = Original Material Costs + Sales Tax

Sales Tax = 5% of Original Material Costs = 0.05 * $2000 = $100

Revised Material Costs = $2000 + $100 = $2100

Revised Overhead Costs = Fixed Cost + Variable Cost

Variable Cost = 2% of (Labor Costs + Material Costs) = 0.02 * ($5500 + $2100) = 0.02 * $7600 = $152

Revised Overhead Costs = $500 + $152 = $652

Total Cost = Revised Labor Costs + Revised Material Costs + Revised Overhead Costs

Total Cost = $5500 + $2100 + $652

Total Cost = $8252

So, with these additional factors, the total cost of the project increases to $8252. This illustrates how a seemingly simple problem can become much more complex with the addition of more variables. When you're facing such problems, break them down step by step. This way you're not overlooking anything. Now, let’s move on to the second problem.

Problem 2: Detailed Solution

For the second problem, let's tackle something a bit different. Suppose the problem states: "A company's revenue increased by 15% in the first year and then decreased by 10% in the second year. What is the net percentage change in revenue over the two-year period?" This type of problem involves percentage changes, which can be tricky if not approached carefully.

First, let’s understand that we can’t simply add 15% and -10% to get 5%. That would be incorrect because the 10% decrease is applied to the new revenue after the 15% increase. Instead, we need to calculate the changes sequentially. Let's assume the initial revenue is $100 for simplicity. This makes it easier to track the percentage changes.

Revenue after the first year (15% increase):

Revenue Year 1 = Initial Revenue + (15% of Initial Revenue)

Revenue Year 1 = $100 + (0.15 * $100) = $100 + $15 = $115

Revenue after the second year (10% decrease):

Revenue Year 2 = Revenue Year 1 - (10% of Revenue Year 1)

Revenue Year 2 = $115 - (0.10 * $115) = $115 - $11.5 = $103.5

Now that we have the revenue after two years, we can calculate the net percentage change:

Net Change = Revenue Year 2 - Initial Revenue

Net Change = $103.5 - $100 = $3.5

Net Percentage Change = (Net Change / Initial Revenue) * 100

Net Percentage Change = ($3.5 / $100) * 100 = 3.5%

Therefore, the net percentage change in revenue over the two-year period is 3.5%. This means that despite the decrease in the second year, the company still experienced an overall increase in revenue compared to the initial year. To further illustrate this, let’s consider a different scenario. What if, instead of a 10% decrease in the second year, the company experienced a 20% decrease?

Revenue after the first year (15% increase) remains the same: $115

Revenue after the second year (20% decrease):

Revenue Year 2 = Revenue Year 1 - (20% of Revenue Year 1)

Revenue Year 2 = $115 - (0.20 * $115) = $115 - $23 = $92

Net Change = Revenue Year 2 - Initial Revenue

Net Change = $92 - $100 = -$8

Net Percentage Change = (Net Change / Initial Revenue) * 100

Net Percentage Change = (-$8 / $100) * 100 = -8%

In this case, the net percentage change in revenue over the two-year period is -8%. This indicates that the company's revenue decreased overall compared to the initial year. This example demonstrates how important it is to perform these calculations sequentially rather than simply adding or subtracting percentages.

Problem 3: Detailed Solution

Let's try a third problem. Consider this: "A car travels 240 miles in 4 hours. What is the average speed of the car in miles per hour?" This problem involves calculating average speed, which is a fundamental concept in physics and everyday life. Knowing how to approach this type of problem is essential.

First, identify the formula for average speed: Average Speed = Total Distance / Total Time. In this case, the total distance is 240 miles, and the total time is 4 hours. Next, plug the values into the formula:

Average Speed = 240 miles / 4 hours

Average Speed = 60 miles per hour

Therefore, the average speed of the car is 60 miles per hour. Let’s add some complexity. What if the car traveled the first 120 miles at 40 miles per hour and the remaining 120 miles at a different speed? What was the car's speed for the second half of the journey?

Time for the first 120 miles:

Time1 = Distance1 / Speed1 = 120 miles / 40 mph = 3 hours

Since the total journey took 4 hours, the time for the second 120 miles is:

Time2 = Total Time - Time1 = 4 hours - 3 hours = 1 hour

Now, we can calculate the speed for the second 120 miles:

Speed2 = Distance2 / Time2 = 120 miles / 1 hour = 120 mph

In this scenario, the car traveled the second half of the journey at 120 miles per hour. To confirm that this is correct, we can calculate the average speed for the entire journey:

Total Distance = 120 miles + 120 miles = 240 miles

Total Time = 3 hours + 1 hour = 4 hours

Average Speed = Total Distance / Total Time = 240 miles / 4 hours = 60 mph

The average speed is still 60 mph, which matches the initial problem. This complex problem highlights the importance of understanding how to break down a problem into smaller, manageable parts.
