Math question that I struggle with

Question

So the task is....''The total cost to rent a kayak is $10 times the number of hours the boat is used. Write an equation to model this situation if c = total cost and h = number of hours.''

All help will be appreciated.

Answer 1

c(h) = 10h

where h is measured in hours

c is measured in dollars

graphically the equation is a straight line through the origin, with slope = 10, h on the x axis, c on the y axis
