9) Your class is visiting an aquarium. Admission is $13 per adult and $8 per student. There are 7 adults
and 27 students. What is the total cost of admission (in dollars)?
Distributive Property:
Use the distributive property to write an equivalent expression that will help you solve the problem using
mental math. Then simplify the expression.
