Answer:
Lowest: Health Styles
Highest: Able
Able is 32.95$ per month
Health Styles is 20$ per month
Crossfit is 24.95 per month
So, Health is the lowest and Able is the highest.
I figured this out by divided the amount by the amount of months. For example, 359.82 divided by 18 is 19.99 which is also the amount per month.
