Question

The cost of a ski ticket is x. Renting ski equipment costs an additional $10. Suzie purchased three tickets and rented 3 sets of equipment. Write an algebraic expression to represent Suzie's total.

Answer 1

Answer: f(x) = 3(x + 10)

Explanation:

1.) It may be a bit easier to understand if x had a value, so let's say it equals 20.

2.) f(20) = 3(20 + 10)

3.) f(20) = 3(30)

4.) f(20) = 90

5.) If the ticket cost $20, then the total would be $90. However, any value can be subbed in for x, so answers can vary.
