Question

You’re trying to decide which cell phone plan to purchase. Plan A charges $40 for a new phone and $20 a month for usage. Plan B provides the phone for free, but has a fee of $30 s month for usage. Write an equation to represent each plan.

Answer 1

m = fee per month for usage

y = total cost/payment

Plan A

y = 20m + 40 (you buy the phone for $40, which is a one time purchase, and have to pay $20 each month)

Plan B

y = 30m (only have to pay $30 each month)

Answer 2

A = 40 + 20x

B = 30x

These answers would just be the equations because Plan B would eventually catch up to Plan A so Plan B is the best option.
