Question
The cost of renting a kayak is 5 for each additional hour. Which of the following represents this situation, where C is the total cost of renting a kayak for h hours?A.C = 5h + 12B.C = 17hC.C = 5(h - 1) + 12D.C = 12h + 5SUBMITarrow_backPREVIOUS
Solution
The correct answer is C. C = 5(h - 1) + 12.
Here's why:
The cost of renting a kayak is $12 for the first hour. This is a fixed cost, so it's a constant in our equation.
For each additional hour, the cost is 12, we need to subtract 1 from the total hours when calculating the additional cost.
So, for h hours, the additional cost is 5 times (h - 1).
Adding the fixed cost and the variable cost gives us the total cost (C), so the equation is C = 5(h - 1) + 12.
