the amount of revenue brought in by states from motor vheicle licenses increased at a relatively constant rate of 499.79 million dollars per year from 1990 to 2000. In 2000, the states brought in 15099 million dollars in revenue from motor vehicle.

a: what was the approximate revenue from licenses in 1990

b: write an equation that give the revenue as a function of the number of year since 1990

c: find the revenue from licenses in 1999

To answer these questions, we can use the information given and some basic math:

a: To find the approximate revenue from licenses in 1990, we know that the revenue increased at a constant rate of 499.79 million dollars per year from 1990 to 2000. The revenue in 2000 was 15099 million dollars. To calculate the revenue in 1990, we can subtract 10 (the number of years between 1990 and 2000) times the constant rate from the revenue in 2000:

Revenue in 1990 = 15099 million dollars - (10 years x 499.79 million dollars/year)

b: To write an equation that gives the revenue as a function of the number of years since 1990, we can use the given constant rate:

Revenue = Constant Rate x Number of Years + Initial Revenue

In this case, the Constant Rate is 499.79 million dollars per year, and the Initial Revenue is the revenue in 1990. Therefore, the equation would be:

Revenue = 499.79 million dollars/year x (Number of Years since 1990) + Initial Revenue

c: To find the revenue from licenses in 1999, we need to calculate the revenue 9 years after 1990 using the equation we derived:

Revenue in 1999 = 499.79 million dollars/year x 9 years + Initial Revenue

499790000
