Answer:
Marcus's access fee per visit is $15.
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.
