5. A gym membership costs $30 to join and $12 each month. Write and use an algebraic expression to find the cost of the gym membership for 6 months.

Respuesta :

30+12 x 6 and it's 12 x 6 first which is 72 so it's now 30+72=$102
y=12(6)+30 
or 
y=12x+30
x is the variable for the number of months.
Y is the total cost of the membership.
