Question

The number of gallons of paint needed to cover a wall is equal to the wall's total area divided by 350.0. the program reads wall area from input, representing a wall's total area. complete the program to output the number of gallons of paint needed to cover the wall, rounded to five digits after the decimal point.

if variable wall area is assigned the value 250.0, then the output is:

Answer 1

The marginal product of the third painter is the difference in productivity when they join, resulting in an additional 75 square feet painted per hour.

Step-by-step explanation:

The marginal product of the third painter is calculated by determining the additional amount of work they contribute beyond what the existing workers can do.

When two painters can paint 200 square feet in an hour, and the addition of a third painter increases the output to 275 square feet, we subtract the initial productivity from the increased productivity to find the marginal product.

So, the marginal product of the third painter is 275 square feet (with three painters) minus 200 square feet (with two painters), which equals 75 square feet.
