One-Step Equations and Properties

What equation matches the scenario?

Amanda and her best friend found some money buried in a field. They split the money evenly, each getting $24.28. How much money did they find?

• $\frac{1}{2}\left(24.28\right)=m$

• $m\div2=24.28$

• $m\times2=24.28$

• $\frac{24.28}{2}=m$
