Answer:
you can only rent the ski boat for about 3 hours.
Explanation:
if you cant spend no more than $150
you need to see how much u can spend within hours.
so you would have to see what 35 can be multiplied to get to 150.
obviously no number multiplied by 35 will get you 150, but if you multiply 35 x 4, you will get 140, which is close enough, yet still you don't have enough for a full 4 hours.
Then you have to consider that you still need to pay $20 just to rent the ski boat alone.
So that will take away from the money you have.
when you subtract 20 from 140, you will still not have enough money for 4 whole hours, therefore you will only have enough for 3 hours with the $ 120 you have left.
lmk if it was right. hope this helps.
