Question

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. Which inequality shows Teresa's gift card balance to be greater than Colin's gift card balance?

Answer 1

Thinking about the equation and the depth I believe that the inequality would be:

100 is greater than 75. If not that I would think the answer is 100-8.50 is greater than 75-6. The last resort would be 12 is greater than 11.
