Answer 1

c) He should add between 1 cup and 2 cups of dirt.

Explanation:

ration of dirt to peat moss:

⇒ 8 parts dirt : 3 parts peat moss

⇒ x cups dirt : 1 cup peat moss

to find the value of dirt, take the ratio and turn it into a fraction

⇒ 8 : 3 =
`(8)/(3)`

⇒ x : 1 =
`(x)/(1)`

⇒
`(8)/(3)` =
`(x)/(1)`

now, we multiply 1 on both sides to isolate x

⇒
`(8)/(3)` x 1 =
`(x)/(1)` x 1

⇒ 2.67 = x

⇒ 2 cups of dirt
