A phone plan costs $40 per month plus $0.10 per text message. Write the linear equation for the total cost (C) based on the number of text messages (t) sent. How would you represent this on a graph?

• C = 40 + 0.05t

• C = 0.10 + 40t

• C = 40 + 0.10t

• C = 40t + 0.10

A subscription service charges $15 per month. Write a linear equation for the total cost (C) based on the number of months (m) subscribed. If you graph this equation, what does the slope represent?

• C = 20m - 5; the slope represents a penalty of $5 for early cancellation.

• C = 15m; the slope represents the monthly cost of $15.

• C = 10m; the slope represents a discount of $10 per month.

• C = 15m + 5; the slope represents a one-time fee of $5.
