Answer 2

I believe the answer is D

Explanation:

For the first 20 towels, the equation is simply 5x. The 5 is the cost per towel ($5) times the number of towels sold up to and including 20 towels.

So the maximum cost of those 20 towels is $5 (20)=$100.

Looking at towels #21 and greater, the price drops to $3 each. Putting this in a formula, you get:

3(x-20)+100 which is $3 for the cost per towel, (x-20) since it starts with towel number 21, and +100 for the cost of the first 20 towels.

Example: Let's try it for 45 towels using the formula:

3 (45-20)+ 100=

3(25) + 100=

75+ 100= $175
