Ryan and Khalil each have their own savings. Together, they borrowed $72 from a friend to buy a gift for their coach. Each has to pay back an equal amount to their friend. Ryan also owes the friend $12. Which explains whether the equation below represents the debt that Ryan owes his friend? StartFraction negative 72 over 2 EndFraction minus (positive 12) = negative 48
It represents the debt because each one owes $36, and Ryan owes an additional $12.
It represents the debt because Ryan has to pay back $36 and he will get back $12.
It does not represent the debt because paying back $12 means that –12 is added, so the result is not –48.
It does not represent the debt because the result should be a positive number since a dollar amount cannot be negative.
