Question

Ginger wants to join a gym. She goes to the local gym and is told that there is a one-time fee of $100 to join and then a monthly fee of $30. If she has belonged to the gym for one year, how much has she paid?

Answer 1

The correct answer is 460

Explanation:

The expression to represent total cost is 30m + 100. If she has belonged to the gym for one year then she has paid for 12 months. Therefore substitute 12 in for m.

30(12) + 100

360 + 100

She has paid a total of $460

Answer 2

She has paid $460 after joining the gym for a year. First there is the joining fee of $100. Then $30 a month for a year is 30 x 12 which equals $360.
