A gym charges $50 dollars per month after an initial membership fee. A member has paid a total of $320 after 6 months. Write an equation that gives the total cost of gym membership as a function of the length of membership (in months).

Respuesta :

x6+50=320

-----------------

x6=50-50=320-50

x6=270

x6/6=270/6

x=45

So this person is spending $45 a month.
