Question

Problem 2.1

To paint a house, a painting company charges a flat rate
of $500 for supplies plus $50 for each hour of labor.
How much would the painting company charge to paint a
house that needs 20 hours of labor? 50 hours of labor?
Enter your answers in the table.
Labor (hours)
20
50
Cost (dollars)

Answer 1

The cost of painting a house that requires 20 hours of labor would be $1500, and for a house that requires 50 hours of labor, the cost would be $3000.

Explanation:

Labor hours: 20 Supplies cost: $500 Labor cost: $50 x 20 = $1000 Total cost: supplies cost + labor cost = $500 + $1000 = $1500

Labor hours: 50 Supplies cost: $500 Labor cost: $50 x 50 = $2500 Total cost: supplies cost + labor cost = $500 + $2500 = $3000

Here is the table with the calculated costs:

Labor (hours) Cost (dollars)

20 $1500

50 $3000

Answer 2

labor cost for 20 hours = $1500

labor cost for 50 hours = $3000

Explanation:

To calculate the cost, we can use the following equation:

Cost = Supplies Cost + Labor Cost

The supply cost is a flat rate of $500, so the labor cost is the only variable.

We can calculate the labor cost by multiplying the number of labor hours by the hourly labor rate:

Labor Cost = Number of Labor Hours × Hourly Labor Rate

The hourly labor rate is $50, so the labor cost for 20 hours of labor is:

Labor Cost = 20 hours × $50/hour

Labor Cost = $1000

Therefore, the total cost for 20 hours of labor is:

Cost = $500 + $1000

Cost = $1500

The same calculation can be done for 50 hours of labor, resulting in a total cost of $3000.
