The county fair charges $1.25 per ticket for the rides. Star bought 25 tickets for the rides and spent a total of $43.75 at the fair. Star spent her money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Write an equation in slope-intercept form to represent the cost for anyone who only pays for ride tickets and fair admission. Use y to represent the total cost and x to represent the number of ride tickets.

First you will have to calculate how much the fair admission costs were.

Star spent $43.75 on rides and the admission together.

One ride ticket costs $1.25, so 25 ride tickets cost:

1.25 x 25 = $31,25

The admission costs will then be:

43.75 - 31.25 = $12.50

A normal linear equation goes like this:

y = c · x

x is supposed to be the number of ride tickets. you add the costs of those tickets in front to show how much money it will be.

y = c · 1.25x

Your constant in this case is the admission, it is the same for everyone, $12.50, so your equation will be:

y = 12.5 · 1.25x
