Question

A local bar and grill is having a quarter wing night during which chicken wings cost a quarter each.

As you leave home to join your friends there, all you grab is a $20 bill. Determine how many wings
you can purchase if you also want to buy a pitcher of your favorite beverage for $5 and ranch dip
for $1.50. There is also sales tax of 8.5%. You will leave a 20% tip on your bill after tax.

Answer 1

Answer: Here is the calculation:

The cost of the wings is $0.25 per wing

The cost of the pitcher of beverage is $5

The cost of the ranch dip is $1.50

Sales tax is 8.5%, so you need to add 8.5/100 * (5+1.5) = 0.0825 to the cost of the beverage and dip.

The cost of the beverage and dip after tax is 5+1.5+0.0825 = 6.5825

The total cost of the wings, beverage, and dip before tip is 6.5825 + 20 = 26.5825

You need to leave a 20% tip, so you need to add 0.2*26.5825 =5.31650 to the total cost

The total cost of the wings, beverage, dip and tip is 26.5825+5.31650 = 31.899

So you have $20 and you want to spend $31.899 including tax and tip, you can purchase 20/0.25 = 80 chicken wings.
