Hi Lawrence!
---------------------------------------------------
We Know:
Powersports Plus: $30 an hour plus a non-refundable deposit of $50.
Sun & Surf: $20 an hour plus a non-refundable deposit of $80.
---------------------------------------------------
Equation:
x = per hour
y = total
Powersports: 30x + 50 = y
Sun and Surf: 20x + 80 = y
---------------------------------------------------
Solution: (Add the deposit then start adding hourly costs)
Powersports: 80, 110, 140
Sun and Surf: 100, 120, 140
---------------------------------------------------
Answer: After <u>3 hours</u> both companies will cost the same amount of money.

Hope This Helps :)
