At silver gym membership is $40 per month, and personal training sessions are $20 each. in one month, how many personal training sessions would sarah have to buy to make the total cost at the two gyms equal?

2 personal training sessions

Step-by-step explanation:

If a personal training sessions is $20, that is 1/2 of the $40 at the Silver Gym. That means if you multiply the $20 by 2, you get the value of the membership which is $40.

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
