Question

The cost of renting a jet ski over a certain number of hours can be represented by the equation y=40x + 50. How much would it cost to rent a jet ski for 3 hours?

Answer 1

$170

Explanation:

Let's say that x represents the amount of hours, so therefore, x will be replaced by 3:

y = (40 * 3) + 50

So, solve inside the parentheses:

y = (40 * 3) + 50

y = 120 + 50

Solve:

y = 120 + 50

y = 170

So, a jet ski would cost $170 to rent for 3 hours

Hope this helps :)
