Question

A person can pay $30 for a membership to the science museum and then go to the museum for just $1 per visit.What is the maximum number of visits a member of the science museum can make for a total cost of $50 ?

Answer 1

20

Explanation:

he has $50 and from there he pays $30 for membership, leaving him $20.

`50 - 3 0 = 20|`

now at the rate of $1 per visit he can make 20 visits.

`20 / 1 = 20`
