Answer:
Explanation:
A jet ski rental is $70.00 for two hours. If you wanted to rent the jet ski for five hours it would cost $130.00.
The first step will be to determine the cost of rental per hour. We would determine it by finding the slope first.
Assuming we plot a graph of cost on the y axis and time on the x axis, from the given equation, our points will be
(2,70) and (5, 130)
Slope = change in y / change in x
Slope = (130 - 70)/5 - 2)
Slope = 60/3 = 20
The next step would be to determine the intercept,c, using the slope intercept form
y = mx + c. Using point (2,70)
70 = 20×2 + c
c = 70 - 40 = 30
The equation is
y = 20x + 30
an equation relating cost, C, to length of rental in hours, h will be
C = 20h + 30
