The image is really unclear but I will assume that the number of teams given = 66
and the formula is
$n = \frac{ {t }^{2} - t }{2}$
plug in the number of teams
$66 = \frac{ {t}^{2} - t }{2}$
multiply both sides by two
$132 = {t}^{2} - t$
subtract 132 from both sides and factor
t = 12

ollegr [7]

Initial cash on hand : $200.00
Ticket cost : $87.96
T-shirt cost per piece: $30.00

The first thing Staci needs to do is to deduct the cost of the ticket from her money.

$200 - 87.96 = $112.04

Stacy has the extra amount of 112.04 to purchase t-shirts. Since, each t-shirt costs $30. To know the number of shirts she can buy, she must divide the difference by 30.

$112.04 / $30 = 3.73

Based from the quotient, Stacy can buy 3 t-shirts.

$30 * 3 = $90 total cost of the tshirts.

$112.04 - 90 = $22.04

After buying the ticket and 3 tshirts, Staci has an excess of $22.04 from her $200.
