The stadium tickets are priced at $29 and $19.  The number of $29-dollar tickets available is  1¹₅ that of the number of $19-dollar tickets. 3 out of 5 of the $29-dollar tickets and all the $19-dollar tickets were sold. The ticket sales amounted to $5982. How much more would have been collected if all the tickets were sold?

	$29	$19
Comparing $29 and $19 tickets at first	6x5 = 30 u	5x5 = 25 u
Before	5x6 = 30 u
Change	- 3x6 = - 18 u	- 25 u
After	2x6 = 12 u	0 u

The number of 29 tickets at first is repeated.  Make the number of 29 tickets the same.  LCM of 5 and 6 is 30.

1¹₅ = ⁶₅

Number of $29 tickets : $19 tickets = 6 : 5

	$29	$19	Total
Number	18 u	25 u
Value	$29	$19
Total value	522 u	475 u	$5982

Total amount collected from the sale of the sold tickets
= 522 u + 475 u
= 997 u

1 u = 5982 ÷ 997 = 6

Number of $29-tickets left unsold
= 12 u 
= 12 x 6
= 72

More amount to be collected if all the tickets were sold
= 72 x 29
= $2088

Answer(s): $2088
