Question

Oscar billed his neighbor a total of $125 for the landscaping work he did. The total cost of the materials was $20 and he charged $14 per hour for his service. How many hours did he work

Answer 1

He worked 7.5 hours

Explanation:

Let's set up an equation!

125 = 14x + 20.

We are trying to find x!

Let's subtract 20 on both (maintain equality) sides

105 = 14x

Now let's divide both(maintain equality) sides by 14 to get!

x = 7.5

Let's check!

125 = 14 * 7.5 + 20

125 = 105 + 20

125 = 125 YES

So, x = 7.5
