Question

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linear relationship between the total cost of belonging to a club and the number of months that you are a member. Each club charges monthly dues, and some clubs require new members to also pay a one-time membership fee.

Answer 1

Hello, welcome to QuestionCove o;
This question may seem a bit confusing however it is actually simple.
You have to compare the cost between the months.
For example, for A 434 divided by 24 is 18. 216 divided by 12 is 18. 108 divided by 6 is 18. So that means that this club does not have an additional starting fee as the price only increased by 18 dollars a month and started at zero. You can check the other two clubs the same way I checked club A
