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?

Respuesta :

6x + 6(3) = 108
6x + 18 = 108
6x = 108 - 18
6x = 90
x = 90/6
x = 15 <== the access fee per visit
