Question: 1 / 400

If a customer buys a bag of dog food for $12.79 with a sales tax of $0.64, how much change will they receive from a $20 bill?

$6.57

To determine how much change the customer will receive from a $20 bill after purchasing a bag of dog food for $12.79 with a sales tax of $0.64, first, you calculate the total cost of the purchase.

The total cost is found by adding the price of the dog food to the sales tax:

\[

Total \, Cost = Price \, of \, Dog \, Food + Sales \, Tax = 12.79 + 0.64 = 13.43

\]

Next, subtract the total cost from the amount given, which is $20:

\[

Change = Amount \, Given - Total \, Cost = 20.00 - 13.43 = 6.57

\]

This calculation shows that the customer will receive $6.57 in change. This amount is correct, as it accurately reflects the difference between the payment and the total expenditure. The other choices do not match the calculated change based on the given purchase details.
