Answer:
Addition.
Step-by-step explanation:
Multiplication is a faster way to do repeated addition.
For example, lets say you would add 10 fifteen's together. Addition would make it:
15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15
= 30 + 30 + 30 + 30 + 30
= 60 + 60 + 30
= 120 + 30
= 150
However, when multiplying:
15 x 10 = 150
As you can tell, multiplication makes it so there are less steps, and is less time consuming.

The answer is C) the slope is 2.50 and the y-intercept is 9, assuming the question refers to the parameters of his monthly cost.
His cost function could be described as y= 2.5x + 9, where x is the number of comic books he purchases. If he buys no comic books, he still has to pay the $9 membership fee.
