Question

Great Rapids White Water Rafting Company rents rafts for $125 per hour. Explain why the point (0,0) and (1,125) are on the graph of the relationship and what these points mean in the context of the problem. How much would you pay for 12 hours? How long have you rented the rafts if you spent $750?

Answer 1

$1500

6 hours

Explanation:

There is no one off fee, therefore we got (0,0) a starting point.

(1,125) is representing the first hour of rent, so 1 hour rent costs $125.

There is a direct relationship between the time and rental fee.

As a function is will be:

• f(x) = 125x, where f(x) is the total amount and x is the time in hours

For x= 12, we get:

• f(12) = 125*12= $1500

So, if f(x) = 750, then:

• 750 = 125x
• x= 750/125
• x= 6 hours
