It costs marcus an access fee for each visit to his gym, plus it costs him $3 in gas for each trip to the gym and back. this month it cost marcus $108 for 6 trips to his gym. how much is marcus's access fee per visit?

Marcus's access fee per visit is $15.

Step-by-step explanation:

Consider the provided information.

It costs Marcus an access fee for each visit to his gym,

Let the access fee for each visit is x.

Plus it costs him $3 in gas for each trip to the gym and back.

Thus the total cost is: x + 3

This month it cost Marcus $108 for 6 trips to his gym.

Now multiply the above expression with 6 and put the value equal to 108.

6(x + 3) = 108

Divide both the sides with 6.

x + 3 = 18

Subtract both the sides by 3.

x = 18 - 3

x = 15

Hence, Marcus's access fee per visit is $15.
