Your dog dug a huge hole in the yard. Your family is wanting to fill it in with dirt. You measure the hole to be 12 feet by 4 feet by 3 feet. If the cost of dirt is $1.25 per cubic foot, how much will it cost your family to fill in this hole?

$180

Step-by-step explanation:

First, we have to find the volume of the hole.

The volume of the hole will be:

V = length * breadth * height

V = 12 * 4 * 3 = 144

The dirt costs $1.25 per , hence, the cost of dirt that will fill the hole will be:

C = $1.25 * 144 = $180

It will cost $180 to fill the hole.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
