Use the pattern to extend the table. Then answer the question below. Include two decimals for each answer even if they are 0 Cars Washed Money Earned (Hint: this is how much you would earn for 1 car) How much is earned per car? $ How much will be earned for 20 cars?

We know that 3 cars yielded $13.50

$13.50 / 3 = $4.50 / 1 car

$4.50 * 12 cars = $54.00

$4.50 * 15 cars = $67.50

$4.50 * 20 = $90.00

38.9 cubic yards

Step-by-step explanation:

We have been a new sidewalk will be 5 feet wide, 280 feet long, and filled to a depth of 9 inches (0.75 foot) with concrete. We are asked to find the amount of concrete required to make the side walk.

The amount of concrete required to make the side walk would be equal to the volume of the sidewalk.

We will use volume of cuboid formula to solve our given problem.

We know that .

Therefore, approximately 38.9 cubic yards of concrete are needed.
