Headline Story
Stella and Keith went to the store. Keith brought 10¢ less than Stella. When they combined their money, they had the exact amount needed to buy two snack bars for 60¢ each.
Possible student responses
- What is the total amount of money Stella and Keith brought?
- Did Keith have enough money for a snack bar?
- The total cost was $1.20.
- If Keith brought 50¢, then Stella brought 60¢, and that is not enough money to buy two bars.
- If Keith brought 60¢, then Stella brought 70¢, and that is too much.
- Keith brought 55¢, and Stella brought 65¢.
