Answer:
Audrey can afford 4 hours of lesson.
Step-by-step explanation:
Given that:
Amount Audrey has to spend = $111
Cost of racket = $55
Cost per lesson = $14
Let,
y be the total cost
x be the number of hours
According to given statement;
y = 14x + 55
111 = 14x + 55
111 - 55 = 14x
14x = 56
Dividing both sides by 14

Hence,
Audrey can afford 4 hours of lesson.
The answer is A. It is not B because 9 is the product of 3 x 3. It can't be C because 1 is only the product of 1 x 1.
