Question

In the United States, the number y (in millions) of bicycles sold with wheel sizes of 20 in. or greater can be modeled by the equation y = 0.3x + 15, where x is the number of years since 1981. In what year were about 22 million bicycles sold?

Answer 1

Answer:

200

Step-by-step explanation:

y=0.3X+15

Let y=22million

22=0.3x+15

0.3x=22-15

x= 7/0.3

x=23.3 years

1981+23.3= 2004.3 , which implies that it was on 2004,
