A car rental company charges a flat fee of $50 plus $0.20 per mile driven. Write a linear equation to represent the total cost (C) in terms of miles driven (m).
C = 50 + 0.50m
C = 50 - 0.20m
C = 0.20m
C = 50 + 0.20m

A delivery service charges a base fee of $10 plus $1.50 per mile. Write the linear equation for the total cost (C) based on miles (m) driven. How would you graph this equation?
C = 10 + 1.5m
C = 10 - 1.5m
C = 1.5m + 5
C = 10 + 2m

A school is selling tickets for a play. The first 50 tickets are $10 each, and after that, they are $8 each. Write a piecewise linear equation to represent the total cost (C) based on the number of tickets (t) sold.
C(t) = { 12t, 0 <= t <= 50; 600 + 10(t - 50), t > 50 }
C(t) = { 10t, 0 <= t <= 100; 800 + 5(t - 100), t > 100 }
C(t) = { 15t, 0 <= t <= 50; 750 + 7(t - 50), t > 50 }
C(t) = { 10t, 0 <= t <= 50; 500 + 8(t - 50), t > 50 }
