+16 140 people were at a soccer match. 80 of them bought the tickets at normal price but the rest bought the ticket at a 20% discount. If the total sale amount of the tickets were $1920, what is the normal price of a ticket?
+129771 Let the normal cost of a ticket = C
At a 20% discount the cost of a ticket = .80C
So....80 people bought tickest at the normal price and 60 bought them at the discounted price
80C + 60 * .80C = 1920
80C + 48C =1920
128C = 1920
C = 1920 / 128 = 15 (dollars) = the normal price
