Charlize Miles · Answer 1

Let n be the number of months that the cost of the memberships fee be the same. Such that for Power plus, the cost would be

23 + 34.65n

For Heavy Hulk, after cooking the new members fee will have a total cost of,

19 + 34.90n

Equating the two,

23 + 34.65n = 19 + 34.90n

The value of n from the equation above is 16. Thus, after 16 months the membership costs will be the same.
