Deshaun and his wife are each starting a saving plan. deshaun will initially set aside $750 and then add $135 every month to the savings. the amount a (in dollars) saved this way is given by the function a=750+135n , where n is the number of months he has been saving. his wife will not set an initial amount aside but will add $485 to the savings every month. the amount b (in dollars) saved using this plan is given by the function b=485n. 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.\
