A recreation center is offering special prices on its pool passes and gym memberships for the summer. On the first day of the offering, a family
paid $96 for 4 pool passes and 2 gym memberships. Later that day, an
individual bought a pool pass for herself, a pool pass for a friend, and 1
gym membership. She paid $72.
Write a system of equations that represents the relationships between
pool passes, gym memberships, and the costs. Be sure to state what
each variable represents.
