Answer:
4 hours will cost $8
Step-by-step explanation:
The question is telling you that each hour of parking costs $2. It is asking you how many hours you have to park to make the cost be $8. In terms of the kind of multiplication fact you might see in 3rd grade, you're asked to fill in the blank in ...
2 × __ = 8 . . . . . . . . cost per hour × hours = total cost
__
In algebra terms, you solve this equation by dividing both sides of it by 2:
(2/2) × __ = 8/2
__ = 4
That is, Mackenzie will pay $8 for parking for 4 hours.

Additional comment
The problem statement is already telling you that the cost is $8. All you're really being asked to find is the corresponding number of hours.
