Can you find an equation (rule) that will satisfy the total cost of the video game if given the original price?Applying to the real world
Natalie is going ice skating. The skating rink charges $6.25 per hour of skating. We will let h represent the amount of hours of skating and c represent the total cost.
Write an equation to match this scenario.
How much would it cost to skate for 1 hour? For 2 hours? For 3 hours?
