Headline Story
Keith has 10¢ more than Stella. Together, they have the exact amount needed to buy 2 bags of popcorn. Popcorn costs less than $1 a bag.
Possible student responses
- The total amount Stella and Keith have must be less than $2.
- If they have enough together to buy 2 bags, then Keith could buy 1 bag himself, because he has more than Stella.
- You don’t know the cost of the popcorn, so you cannot say how much money they have.
