Keisha and her husband are each starting a saving plan. Keisha will initially set aside $75 and then add $20.55 every week to the savings. The amount A (in dollars) saved this way is given by the function
A = 75+ 20.55 N, where N is the number of weeks she has been saving.
Her husband will not set an initial amount aside but will add $70.55 to the savings every week. The amount B
(in dollars) saved using this plan is given by the function B = 70.55N.
Let T be total amount (in dollars) saved using both plans combined. Write an equation relating T to N.
Simplify your answer as much as possible.
