Consider two situations: Situation 1: In Lakeville, Melinda’s television cable bill is a flat rate of $50 per month, plus $1.50 for every movie she rents. After one month of service, her bill is $66.25.

Situation 2: In Oceanside, Kimberly’s television cable bill is a flat rate of $60 per month, plus $1.25 for every movie she rents.

If you were to model these two situations with equations to solve for all the unknowns, what similarities and differences would the equations have? Can you solve for all the unknowns in both situations?
