Question

The amount a car dealership earns for selling a car is directly proportional to the price of the car. The table shows this relationship.

What is the constant of proportionality?

Car price ($) (x) 20,000 30,000 40,000
Amount earned ($) (y) 1000 1500 2000

Answer 1

I think its 2 because if you divide 20,000 over 1000 you get 2. If you do that for the other values, you would also get 2.
