The number of hours that the kayak rented for the total costs to be the same will be 2 hours.
How to illustrate the information?
At 1 hour, the cost will be:
y = 7x + 9
= 7(1) + 9 = 16
At 2 hours, cost will be:
y = 7x + 9
y = 7(2) + 9
= 23
It should be noted that in the table, at 2 hours the cost is $23 also. Therefore, the number of hours that the kayak rented for the total costs to be the same will be 2 hours.
