PSLE At a carnival, 20% of the tickets were sold at full price and 15% of the tickets at half price. The remaining 650 tickets were given away free. The total amount of money collected was $14850. What was the price of the ticket at half price?
Percentage of the tickets given free
= 100% - 20% - 15%
= 65%
65% → 650
1% → 650 ÷ 65 = 10
Number of tickets sold at full price
= 20% of the tickets
= 20 x 10
= 200
Number of tickets sold at half price
= 15% of the tickets
= 15 x 10
= 150

Cost of 1 full price ticket = 2 u
Cost of 1 half price ticket = 1 u
Total amount collected
= 200 x 2 u + 150 x 1 u
= 400 u + 150 u
= 550 u
550 u = 14850
1 u = 14850 ÷ 550 = 27
Price of the ticket at half price
= 1 u
= $27
Answer(s): $27
