In Exercises 49–54, assume that a constant rate of change exists for each model formed.
Revenue from Gas Taxes. As a result of cars getting better gas mileage, the increased use of electric vehicles, and fewer miles being driven, revenues from U.S. gas taxes are declining. It is projected that the gas-tax revenue will drop from $24.1 billion in 2017 to $20.3 billion by 2025. Let
a. Find a linear function that fits the data.
b. Use the function of part (a) to estimate the projected gas tax revenue in 2019 and in 2023.
c. At this rate of decrease, when will the gas tax revenue be $19.8 billion?
