Question

A gym membership costs $50. Each exercise class is an additional cost. Jacob took 8 exercise classes and spent $90 last month on his gym membership.

Given that x represents the cost of an exercise class, which model shows how to find the cost of each exercise class ?

Answer 1

Answer: 90 = 50 + 8x

Step-by-step explanation: This is so because we do not know how much each class costs. We know that a membership is $50 and he took 8 classes. You would multiply x by 8 to find the cost of the classes and add that to 50 to get your final answer of 90. That being said.... x = 5.
