Melvin ordered a cinnamon roll, 3 doughnuts, and 2 dozen doughnut holes. The sales tax was $0.72. He paid with a $20 bill.
How much change should Melvin receive from a $20 bill?
First, calculate the total cost of Melvin's order.
1 cinnamon roll = $2.00
3 doughnuts = $3.00
2 dozen doughnut holes = 24 doughnut holes = $6.00
Total cost before tax = $2.00 + $3.00 + $6.00 = $11.00
Add the sales tax of $0.72 to the total cost.
Total cost after tax = $11.00 + $0.72 = $11.72
Subtract the total cost after tax from the $20 bill to find out how much change Melvin should receive.
$20.00 - $11.72 = $8.28
Melvin should receive $8.28 in change.
