Answer:
rental fee = $6
average cost for 6 hours = $2.50/hour.
Step-by-step explanation:
x + 1.50*6 = 15 where x = the initial rental fee
x + 9 = 15
x = $6
The rental fee is $6.
For 6 hours, the cost per hour works out to 15/6 = $2.50
So the Correct answer would be all three of them.
This includes 27:18, 12:8, and 21:14.
The math behind this includes proportions.
For instance, if you multiple 3 by 9, you get 37. You have to multiple 2 by 9 now, and you should get 18. This is how all three of the answers are correct!
