Explanation:
13. A school is planning an excursion for all of their students to see the
penguins on Phillip Island. They find a company who can provide
two different types of coaches for the trip: one that holds 34
passengers and one that holds 51 passengers. The coach company
has 8 of the smaller coaches and 4 larger coaches available.
The hire cost $500 for a smaller coach and $700 for a larger coach.
If there are 374 students and teachers going on the trip,
determine the minimum total cost for the coach hire.
