Answer:
The cashier is most likely correct, and Anna's claim is incorrect. If Anna gave the cashier two $10.00 bills, then the total amount of money she gave the cashier would be $20.00. If she received $4.51 in change, then the cost of the purchase would be $15.49.
Explanation:
We can use the following equation to calculate the cost of the purchase:
Total cost of purchase = amount given - amount of change
In this case, we can substitute the values we know:
Total cost of purchase = $20.00 - $4.51
Total cost of purchase = $15.49
Therefore, the cost of Anna's purchase was $15.49, and the cashier gave her the correct amount of change. If Anna had received $14.51 in change, the cost of her purchase would have been $20.00 - $14.51 = $5.49, which is not consistent with the price of a typical purchase. Therefore, it is likely that the cashier gave Anna the correct change.
