please help me write algebraic equation/ solution if membership for local zoo is $135, members do not pay admission but they are charged $3. to park . nonmembers admission is $25. for the zoo and $5. for parking. After how many visits have members and nonmembers paid the same amt? I believe answer is 5 visits
135 +( 5 x 3) = 5(25) + 5(5)
150 = 150

after n visits
cost for members = 135 + 3n
cost for nonmembers = 25n + 5n = 30n
when is 30n = 135 + 3n ?
27n = 135
n = 135/27 = 5
you are correct
