A car rental company charges a flat fee of $20 plus $0.15 per mile driven. Write a linear equation to represent the total cost (C) in terms of miles driven (m). What is the slope and what does it represent in this context?
C = 20 + 0.20m; Slope = 0.20 (cost per mile)
C = 20 + 0.15m; Slope = 0.15 (cost per mile)
C = 20 + 0.10m; Slope = 0.10 (cost per mile)
C = 15 + 0.15m; Slope = 0.15 (base fee)

If a store sells notebooks for $2 each and charges a $5 service fee, write the linear equation for the total cost (C) in terms of the number of notebooks (n). What is the y-intercept and what does it signify?
C = 2n + 5; y-intercept = 5, signifies the service fee.
C = 3n + 5; y-intercept = 5, signifies the total cost.
C = 2n; y-intercept = 0, signifies no service fee.
C = 2n + 10; y-intercept = 10, signifies a discount.

A phone plan costs $25 per month plus $0.10 per text message. Write the equation for the total cost (C) based on the number of text messages (t) sent. What does the slope represent?
C = 25 + 0.10t; the slope represents the cost per text message.
C = 25 + 0.05t; the slope represents the number of text messages.
C = 0.10 + 25t; the slope represents the monthly fee.
C = 25t + 0.10; the slope represents the total cost.

A delivery service charges $5 for the first mile and $1.50 for each additional mile. Write the equation for the total cost (C) based on the number of miles (m) driven. What is the slope and what does it represent?
C = 3.5m + 5; slope = 3.5, representing the cost for the first mile.
C = 5m + 1.5; slope = 5, representing the total cost per mile.
C = 1.5m + 5; slope = 1.5, representing the initial fee.
C = 1.5m + 3.5; slope = 1.5, representing the cost per additional mile.
