Problema Solution
To become a member of a skating rink, you have to pay a memebership fee of $30. The cost of admission to the rink for members is $5 and for nonmembers $7. How many visits, including the membership fee be the same as the total cost for members and nonmembers?
Answer provided by our tutors
let 'x' be the number of visits
the member will pay: 3
the non-member will pay: 7x
we need to find x so that
30 + 5x = 7x
7x - 5x = 30
2x = 30
x = 15
the cost will be the same for members and non-members after 15 visits.
