Question

Samantha is painting her house. There are a total of 2,261 square feet of surface area to be painted. If she can paint 75 square feet of surface area per hour, which equation would represent A, the surface area of the wall left to paint, after she Samantha has painted for t hours?

Answer 1

The surface area of the wall left to paint after painting for t hours will be; (2,261 -75t) square feet

Explanation:

Here, we want to calculate the size of the surface area left to paint.

From the question, we are told that she can paint 75 square feet by hour

So in t hours, the total surface painted will be 75 * t = 75t square

To get the surface area left to paint, we simply subtract from the total

That will be (2,261 - 75t) square feet
