A car rental agency rents sedans at $45 a day and convertibles at $65 a day. If one day...?

Rufus Plough: Let s = the number of sedans rented per dayLet c = the number of convertibles in that day.(1) s + c = 32Cost times quantity equal total rental money(2) s * 45 = total cost of the sedan rentals(3) c * 65 = total cost of the convertible rentals(4) (s * 45) + (c * 65) = total revenue = $1680Since, from equation (1) s = 32 - c, we get:[(32 - c) * 45] + 65c = 1680(1440 - 45c + 65c = 1680The rent is for 12 convertibles and 20 sedans....Checking (12 * 65) + (20 * 45) = 780 + 900 = 1680.....The answer checks and is xorrect.20c = 1680 - 1440 = 240....Show more

Sol Bayn: You better answer it this way.let x= sedans and y=convertiblesx+y=3245x+65y=1680and solve for y.y=12....Show more

Jess Grizzel: OK NM I think I got it: 45x + 65y = 1680-45x - 45y = -1440 20y = 240 y = 12 super...Show more
