Answer:

The equation would be 7.50x + 15=90

Step-by-step explanation:

So the the total you are trying to find is 90. So the equation would equal 90. Now since we are trying to find a unknown variable we use x. This results in 7.50x. Now 15 is a known variable so it will just stay the same. The amount of hours would be 10.
