Models that approximate the numbers N of DVDs rented are SN = 342 - 20x {N = 22 + 20x Horror film Comedy film where x represents the week, with x = 1 corresponding to the first week of release. (a) After how many weeks will the numbers of DVDs rented for the two films be equal? weeks (b) Use a table to solve the system of equations numerically. Compare your result with that of part (a). Weeks, x N = 342-20x 1 2 N = 22 + 20x 3 4 5 6 7 8 9 10 The rentals are equal when x = weeks.
