The function C(x) = 49.5x + 19.5 represents the cost (in dollars) of buying x concert tickets. How much does it cost to buy four

Reika [66]

To buy four tickets it would cost $217.5 because
C(x) = 49.5(4) +19.5
C(x) = 198 +19.5
C(x) = 217.5
With $465 you could buy 9 tickets.
C(x) = 49.5(9) +19.5
C(x) = 445.5 + 19.5
C(x) = 465
