Question

Harry pays $28 for a one month gym membership and has to pay $2 for every fitness class he takes. This is represented by the following function, where x is the number of classes he takes.

What is the total amount Harry has to pay if he takes 12 classes?

Answer 1

Answer: Harry has to pay $52 altogether.

To find out the answer, the number of classes Harry takes, you can represent it by multiplying the 12 classes by $2 each, $24, and then adding $28 to $24 to find out the total cost of the member ship and the fitness classes.

Answer 2

Harry has to pay $52. $28 at the start, and then 12x2=$, so $28+$24=$52
