Carmen wants to buy a snack that costs $3.74 including tax. Carmen gives the cashier $10. Which equation can be used to find the amount of change, x, that Carmen receives? How much change did she receive?
The equation that can be used to find the amount of change, x, that Carmen receives is:
x = amount given - cost of the snack
Substituting the given values, we have:
x = $10 - $3.74
x = $6.26
Carmen received $6.26 in change.
