Answer:

12 lunches.

Step-by-step explanation:

Theresa:

$8.50 * 11 = $93.50 so she can buy 11 lunches with her gift card.

Colin:

$6 * 12 = $72 so he can buy 12 lunches with his gift card.

So Colin can buy one more lunch than Theresa. Therefore, if Theresa buys 12 lunches, she will go over her gift card.
