Problema Solution
Individual tickets to a raffle cost .35. A pair of consecutively numbered tickets may be bought for .50. If 100 tickets were sold and $32.20 was collected, how many people purchased pairs of consecutively numbered tickets?
Answer provided by our tutors
let
x = the number of individual tickets sold
y = the number of paired tickets sold
x + y = 100
0.35x + (y/2)0.50 = 32.20
by solving the above system of equations we find
x = 72 tickets
y = 28 tickets
