Question

It says a grocery store is giving a reusable bag to every person who donates more than $5 to charity. Ella donates $5.50. Will she get a bag? Explain how you know.

Answer 1

Yes, we can verify using subtraction:

If we subtract 5 from 5.5 and the result is positive we can conclude 5.5 is greater than 5, if the result is negative, we can conclude 5.5 is less than 5, so:

`\begin{gathered} 5.5-5=0.5 \\ 0.5>0 \end{gathered}`

Since 0.5 > 0, the result is positive, therefore 5.5 is greater than 5. Therefore Ella will get a bag.
