Solve the equation.
4x - 3/5 = 2/5

a. 1/5
b. 5/5
c. 1/2
d. 1/4

The answer is $738.

Step-by-step explanation:

The center has one square 32 feet on each side.

One circular playground with a 30 feet diameter.

One rectangular playground 30 feet wide and 45 feet long.

The center people are putting the mulch to a depth of 6 inches or 0.5 feet.

We have to find the volumes of all grounds:

The volume of the square playground is ft³  

The volume of the circular playground is ft³  

The volume of the rectangular playground is ft³

So the total volume of rubber needed = ft³

The given price is in yards so 1 cubic yard is equal to 27 cubic feet.

So, for 3 feet per yard the volume of rubber is = yard³

Given price is $12.50 per cubic yard so, for 57.04 cubic yards, the price will be:

dollars

Adding the delivery cost of $25.  

The grand total is dollars

Hence, the answer is $738.
