Exploring Costs: Solving Equations & Graphing Changes

A car rental company charges a flat fee of $50 plus $0.20 per mile driven. Write an equation to represent the total cost (C) based on the number of miles driven (m). What is the initial value and the rate of change?

• C = 30 + 0.20m; Initial value: 30; Rate of change: 0.20

• C = 50 + 0.20m; Initial value: 50; Rate of change: 0.20

• C = 50 + 0.10m; Initial value: 50; Rate of change: 0.10

• C = 50 + 0.50m; Initial value: 50; Rate of change: 0.50
