x + 3.74 = 10; Carmen receives $6.26 in change.
x + 10 = 3.74; Carmen receives $13.74 in change.
x - 3.74 = 10; Carmen receives $13.74 in change.
x - 10 = 3.74; Carmen receives $6.26 in change.
The correct equation to find the amount of change, x, that Carmen receives is:
x = 10 - 3.74 (Carmen paid $10 and the snack costs $3.74)
Calculating this equation, we get:
x = 6.26
Therefore, Carmen receives $6.26 in change.
So, the correct option is:
x - 3.74 = 10; Carmen receives $6.26 in change.
