If the amount of money brought in by the states from motor vehicle licenses increased at a relatively constant rate of 499.79 million dollars per year from 2000 to 2010. In 2010, the states brought in $15,099 million in money from motor vehicle licenses. How much money was brought in from licenses in 2000?

After x years,

y = 499.79x + b
since y(10) = 15099, you need to find b such that
499.79*10 + b = 15099
b = 10101.10
