Question

Jason and his friends want to go bowling on Friday night. Southgate Bowling Alley charges $30 shoes and $6 per hour to bowl, while Glades Bowling Alley charges $36 for shoes and $3 per hour to bowl. At how many hours would it be the same cost at either bowling alleys?

Answer 1

2 hours

Explanation:

Slope represents the hourly rate.

Constant represents initial price.

`y = 30 + 6x \\ y = 36 + 3x \\ 30 + 6x = 36 + 3x \\ 3x = 6 \\ x = 2`
