C.) Point (15, 180) represents the unit rate of profit
D.) Point (20, 240) represents the profit for selling 20 scarves
E.) Point (240, 20) represents the profit for selling 20 scarves

Answer 1

A. and D.

Explanation:

To get the unit rate, you divide the y value by the x value.

180/15 = 12

The x value becomes a 1.

This means A. is correct.

Take the unit rate to find the profit for 20 scarves. To get 20, you multiply 1 by 20.

1 * 20 = 20

Do the same to 12.

12 * 20 = 240

This will give you the point (20, 240).

This means D. is correct.
