PSLE At a soccer match, 25% of the tickets were sold at full price and 50% of the tickets at half price. The remaining 175 tickets were given away free. The total amount of money collected was $18900. What was the full price of the ticket?
Percentage of the tickets given free
= 100% - 25% - 50%
= 25%
25% → 175
1% → 175 ÷ 25 = 7
Number of tickets sold at full price
= 25% of the tickets
= 25 x 7
= 175
Number of tickets sold at half price
= 50% of the tickets
= 50 x 7
= 350

Cost of 1 full price ticket = 2 u
Cost of 1 half price ticket = 1 u
Total amount collected
= 175 x 2 u + 350 x 1 u
= 350 u + 350 u
= 700 u
700 u = 18900
1 u = 18900 ÷ 700 = 27
Full price of the ticket
= 2 u
= 2 x 27
= $54
Answer(s): $54
