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.

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)

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
