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.
