Question

Write an equation then solve

it cost $4 to enter the fair each ride cost $2.50 you have $21.50 how many rides can you go on?

Answer 1

Equation: y= 2.50x + 4

21.50 divided by 2.50
= 8.6

You can go on 8 rides.

Answer 2

$21.50 - $4 = $17.50 If you start with $21.50, subtract the $4 entrance fee, you have $17.50 left to spend on rides. To figure out how many rides you can go on, divide $17.50 by $2.50. You can go on 7 rides. Here's the equation:

(21.5-4)/2.5=amount of rides

(21.5-4)/2.5= 7 rides
