The amount of change that Melvin would receive from a $20 bill is equal to: C. $11.78.
How to determine Melvin's change?
In order to determine the amount of change that Melvin would receive from a $20 bill, we would first of all calculate the total cost before tax.
For the cinnamon roll, we have:
Cinnamon roll's cost = $2.59.
For three (3) doughnuts, we have:
Doughnut's cost = 0.95 × 3
Doughnut's cost = $2.85.
For two (2) dozen doughnut holes, we have:
Doughnut hole's cost = 1.75 × 2
Doughnut hole's cost = $3.5.
Total cost = $2.59 + $2.85 + $3.5
Total cost = $8.94
Next, we would determine the new cost after applying sales tax:
New cost = 8.94 - 0.72
New cost = $8.22.
Now, we can determine Melvin's change:
Change = Dollar bill - New cost
Change = $20 - $8.22.
Change = $11.78.
