11) Ms. Ripa's family is planning to come visiting her from New York. She hopes to take
them to some of the National Parks in Utah while they are here, but she needs to save up to
buy their tickets. Adult tickets are $12 each, and child tickets are $7 each. If she has 5 adults
and 4 children coming to visit, how much money will she need to save up to buy all of their
tickets?
