the amount of revenue brought in by states from motor vehicle licenses increased at a relatively constant rate of 499.79 million dollars per year from 1990 to 2000. In 2000, the states brought in 15,099 million dollars in revenue from motor vehicle licenses.

a: what was the approximate revenue from licenses in 1990?

b: write an equation that gives the revenue as a function of the number of years since 1990.

c: find the revenue from licenses in 1999.

  • math help please -

    a. y = mx + b

    15099 = 499.79(10) + b
    b = 10101.1
    y = 499.79x + 10101.1

    b. y = 499.97x + 10101.1
    y = 499.79(0) + 10101. 1
    y = $10101.1
    c. y = 499.79x + 10101.1
    y = 499.79(9) + 10101.1
    y = $14599.21
