Question

I'm stuck, can anyone help?

A jetski rental company charges a $50 deposit, plus $25 per hour to rent a jetski. This can be represented by the formula T = 25h + 50, where T is the total cost, and h is the number of hours rented. What would change the y-intercept of the equation?

A) rent for more hours
B) rent for fewer hours
C) changing the deposit to $40
D) changing the hourly rate to $30

Answer 1

i think the answer is C

Answer 2

Answer: c) Changing the deposit to $40

Step-by-step explanation: The y-axis in the formula T = 25h + 50 is represented by the total cost (T) and x-axis is the number of hours rented (h).

For the graphic to intercept the y-axis, x must be zero, in other words:

when h=0, T=50.

So, change in the y-intercept will occur if you increase or decrease the deposit for the jetski rental.
