Teresa has a $100 gift card to her favorite restaurant. Each day, she uses her gift card to buy the same lunch for $8.50. Colin has a $75 gift card to the same restaurant. His lunches cost $6 each. For what numbers of lunches will Teresa's gift card balance be greater than Colin's gift card balance?

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.
