Answer 1

To determine who is correct, let's calculate the correct change Anna should have received.

Anna gave the cashier two $10.00 bills, which adds up to $20.00.
The change Anna should have received is $20.00 (total amount given) - $4.51 (change given) = $15.49.

Now, let's compare the calculated change ($15.49) to Anna's claim of $14.51.

If the cashier had given Anna $14.51 in change instead of $4.51, Anna would have received a total of $24.51. However, since Anna only gave the cashier $20.00, it is not possible for her to receive $24.51 in change.

Based on this calculation, it can be determined that the cashier was correct in giving Anna $4.51 in change. Anna's claim of $14.51 is incorrect.
