The safari park tickets are priced at $22 and $14.  The number of $22-dollar tickets available is  2²₃ that of the number of $14-dollar tickets. 2 out of 3 of the $22-dollar tickets and all the $14-dollar tickets were sold. The ticket sales amounted to $4302. How much more would have been collected if all the tickets were sold?

	$22	$14
Comparing $22 and $14 tickets at first	8x3 = 24 u	3x3 = 9 u
Before	3x8 = 24 u
Change	- 2x8 = - 16 u	- 9 u
After	1x8 = 8 u	0 u

The number of 22 tickets at first is repeated.  Make the number of 22 tickets the same.  LCM of 3 and 8 is 24.

2²₃ = ⁸₃

Number of $22 tickets : $14 tickets = 8 : 3

	$22	$14	Total
Number	16 u	9 u
Value	$22	$14
Total value	352 u	126 u	$4302

Total amount collected from the sale of the sold tickets
= 352 u + 126 u
= 478 u

1 u = 4302 ÷ 478 = 9

Number of $22-tickets left unsold
= 8 u 
= 8 x 9
= 72

More amount to be collected if all the tickets were sold
= 72 x 22
= $1584

Answer(s): $1584
