Lisa and her husband are each starting a saving plan. lisa will initially set aside $ 125 and then add $ 50.85 every week to the savings. the amount a (in dollars) saved this way is given by the function = a + 50.85 n 125 , where n is the number of weeks she has been saving. her husband will not set an initial amount aside but will add $ 75.65 to the savings every week. the amount b (in dollars) saved using this plan is given by the function = b 75.65 n . 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.
