Question

A water park charges a rental fee plus $1.50 per hour to rent inflatable rafts. The total cost to rent a raft do 6 hours is $15. Assume the relationship is linear. Find and interpret the rate of change and the initial value.

Answer 1

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
