Question

Ryan earns $20 for every lawn that he mows. Which set of ordered pairs represents the relationship between the number of lawns Ryan mows and the money he earns?

Answer 1

independent variable = x = 20

dependent variable = y = money he earns

The equation is

y= 20x

where x is the number of lawns that he mows, and y is the money that he earns.

So, for 1 lawn: x=1

y= 20(1)

y= 20

So, (1,20)

For 2 lawns:

y= 20(2) =40

(2,40)

For 3:

y= 20(3) = 60

(3,60)

answer: (1,20), (2,40) , (3,60)
