Mary and her husband are each starting a saving plan. Mary will initially set aside $650 and then add $145 every month to the savings. The amount A (in dollars) saved this way is given by the function A=650+145N, where N is the number of months she has been saving.

Her husband will not set an initial amount aside but will add $595 to the savings every month. The amount B (in dollars) saved using this plan is given by the function B=595N.

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.
