Zoe, Minh, and Jake sold some tickets for a school fundraiser. Each ticket cost $2. Zoe sold 1/2 of the tickets. Minh and Jake sold the remaining tickets in the ratio 1:3. If Zoe sold 36 more tickets than Minh, how much money dis the 3 students collect altogether?

Answer 1

tickets sold by Minh --- x
tickets sold by Jake --- 3x
(notice x : 3x = 1 : 3)

So number of tickets sold by Zoe = 4x

4x - 36 = x
3x = 36
x = 12

total tickets = x+3x + 4x = 8x or 96
money collected = 96($2) = $192
