Final answer:
The subject is Mathematics for Middle School. The calculation involved determining the total cost of the items purchased, the total amount given to the cashier, and the correct change due which is $0.16.
Step-by-step explanation:
The student's question involves performing basic arithmetic operations to calculate the total cost of items purchased, the amount given to the cashier, and the change due to the customer. To find the total cost of the items, one must multiply the quantity of each item by its price and then add up these amounts. For example, if a customer buys 10 apples at 50 cents each, the cost for the apples would be $5.00. Similarly, purchasing 6 cloves of garlic at 29 cents each would cost 6 x $0.29 = $1.74.
For the question given, the calculation would be:
- Apple pie: $8.04
- Garlic (6 x $0.29): $1.74
- Quart of milk: $1.31
Total cost = $8.04 + $1.74 + $1.31 = $11.09.
The customer gives $5 + six $1 bills + $0.25, which equals $11.25. The change due back to the customer would be the amount given minus the total cost, $11.25 - $11.09 = $0.16, as the register indicates.
