Question

Steve just signed a lease to rent a new apartment. His monthly rent will be $800.00, and he will have to pay a one-time nonrefundable security deposit equal to half of the monthly rent. If Steve rents the apartment for x months, which equation can be used to determine T, the total amount Steve will pay to live in the apartment?

Answer 1

since the one time fee is half of 800 which is 400 thats your "b" value in y=mx+b.

and you constant rate is 800, where x equals numbert of months, so its 800x

T is the total, so your equation is

T=800x+400
