Question

The formula for c the cost of a painter, is c = 20h + 35 where h represents the number of hours the painter worked on a job A homeowner has $125 to spend on painting Which equation could be used to find the number of hours that a painter can work?

Answer 1

Option (2)

Explanation:

Formula for c the cost of a painter is,

c = 20h + 35

Here, h = hours the painter worked

If a homeowner has total amount $125 to spend on painting,

So, for c = 125,

125 = 20h + 35

(20h + 35) - 35 = 125 - 35

20h = 125 - 35

`(20h)/(20)=((125-35))/(20)`

h =
`((125-35))/(20)`

Therefore, Option (2) will be the answer.
