A swimming pool is a rectangular prism. The pool is 36 feet long and 20 feet wide. What is the total amount of water, in cubic feet, needed to fill the pool to a depth of 4feet?

Step-by-step explanation:

The computation of the total amount of water needed could be determined by using the volume formula which is shown below:

where

L = length,

W = width,

and D = depth.

Now putting the values to the above formula

Therefore, the  total amount of water needed is

We simply applied the above formula

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
