It costs a general admission fee of $6 to get into the fair and then $1 for each ride. which of the following equations would represent the total cost to ride x rides at the fair? f(x) = 6x f(x) = 7x f(x) = 6 + x

The equation that will represent the total cost to ride x rides at the fair is f(x)=6+x

Step-by-step explanation:

We know that the amount to enter the fair is $6 for admission fee. To ride on each ride costs $1. Therefore:

The total amount to ride and enter the fair if you want to ride x rides is:

The admission fees to enter the fair must be included because without paying the admission fees, you will not be allowed to ride on the rides. This contributes to the x amount of rides you will take at $1 each.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
