Answer:
James is paid $3 per square foot
Step-by-step explanation:
We are given that the wall has a rectangular shape with dimensions 30 feet and 15 feet
The area of the rectangle is the product of its length and width
This means that:
Area of wall to be painted = 30 × 15 = 450 ft²
Now, we know that James will be paid $1350 for the whole project
This means that he will be paid $1350 for painting 450 ft²
To know how much is being paid for one square foot, we will simply divide the total payment by the area to be painted
This means that:
James is paid
dollars per square foot
Hope this helps :)
