The theme park tickets are priced at $22 and $15.  The number of $22-dollar tickets available is  2²₃ that of the number of $15-dollar tickets. 3 out of 4 of the $22-dollar tickets and all the $15-dollar tickets were sold. The ticket sales amounted to $1062. How much more would have been collected if all the tickets were sold?

	$22	$15
Comparing $22 and $15 tickets at first	8x1 = 8 u	3x1 = 3 u
Before	4x2 = 8 u
Change	- 3x2 = - 6 u	- 3 u
After	1x2 = 2 u	0 u

The number of 22 tickets at first is repeated.  Make the number of 22 tickets the same.  LCM of 4 and 8 is 8.

2²₃ = ⁸₃

Number of $22 tickets : $15 tickets = 8 : 3

	$22	$15	Total
Number	6 u	3 u
Value	$22	$15
Total value	132 u	45 u	$1062

Total amount collected from the sale of the sold tickets
= 132 u + 45 u
= 177 u

1 u = 1062 ÷ 177 = 6

Number of $22-tickets left unsold
= 2 u 
= 2 x 6
= 12

More amount to be collected if all the tickets were sold
= 12 x 22
= $264

Answer(s): $264
