A moving truck rental company charges $20.95 to rent a truck, plus $0.92 per mile. What is the formula for C(d), the total cost of renting the truck for one day if you drive d miles?

• C(d) = 20.95 + 0.92d

• C(d) = 20.95d + 0.92

• C(d) = 0.92 + 20.95d

• C(d) = 0.92d - 20.95

A town's population was 45,000 in 2003 and has been growing by 2700 people each year. What is the equation for the population, P, x years after 2003?

• P = 45000 + 2700x

• P = 45000 - 2700x

• P = 2700x - 45000

• P = 2700 + 45000x

A town's population has been growing linearly. In 2003, the population was 68,500. The population has been growing by 2700 people each year. Write an equation for the population, P, x years after 2003.

• P = 68,500 + 2700x

• P = 68,500 - 2700x

• P = 2700x - 68,500

• P = 2700 - 68,500x

A car rental company charges a base fee of $30 and $0.50 per mile driven. What is the formula for the total cost, C(m), if you drive m miles?

• C(m) = 30 + 0.50m

• C(m) = 30m + 0.50

• C(m) = 0.50 + 30m

• C(m) = 0.50m - 30
