Answer:
The volumes of four rectangular prism are 16,54,128,250 cubic feet.
Step-by-step explanation:
Given : One company makes inflatable swimming pools that come in four sizes of rectangular prisms. the length of each pool is twice the width and twice the depth. the depth of the pools are each a whole number from 2 to 5 feet. If the pools are filled all the way to the top.
To find : What is the volume of each pool?
Solution :
Let x be the height of the pool,
The depth of the pools are each a whole number from 2 to 5 feet i.e. 2,3,4 and 5.
According to question,
The length of each pool is twice the width and twice the depth.
So, width = x , length = 2x and height = x
The equation form to find volume is
Now,
At x=2
At x=3
At x=4
At x=5
Therefore, The volumes of four rectangular prism are 16,54,128,250 cubic feet.

Answer:
Let charge per day be $x and charge per mile be $y
then:
as per the given condition we have;
3x + 300y =159 .....[1]
5x + 600y = 289 .....[2]
Multiply equation [1] both sides by 5 we get;
Using distributive property:
15x+1500y = 795 .....[3]
Multiply equation [2] by 3 both sides we get;
Using distributive property:
15x+1800y = 867 .....[4]
Subtract equation [3] from [4] to eliminate x and solve for y;
15x+1800y-15x-1500y = 867 -795
Combined like terms;
300y = 72
Divide both sides by 300 we get;
⇒ y =$0.24 per mile.
Now substitute this value y in equation [1] to solve for x;
3x + 300(0.24) =159
3x + 72 =159
Subtract 72 both sides we get;
3x + 72 -72 = 159 -72
Simplify:
3x = 87
Divide both sides by 3 we get;
Therefore, the best rental charges per day is, $ 29 and the charges per mile is, $0.24
