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?

No

Explanation:

If Teresa has a $100 Gift Card and her lunch is $8.50 everyday, $8.50 x 10 = 10 Lunchs for a total of $85 then add one more which = 11 Lunchs for a total of 93.50, this means she can not buy another lunch, Colin has a $75 gift card and his lunch is $6 everyday, so $6 x 10 = $60 for a total of 10 lunchs plus add 2 which is 12 lunchs for a total of $72 which means No Teresa's Gift Card Will Not Be Greater In Lunchs.
