Question

The Win went out for dinner. Dinner cost $80. If the tax was 8% and they left a 20% tip on the cost of the dinner before tax, what was the total bill?

Answer 1

Dinner cost = $80

tax = %8

tip = %20 before tax

Multiply the dinner cost buy the tax percentage in decimal form ( divided by 100)

Tax amount =80 x (8 /100 ) = 80 x (0.08 ) = $6.4

Same process for the tip amount:

Tip amount = 80 x (20/100) = 80 x 0.2 = $16

Add both amounts to the dinner cost

Total bill = 80 + 6.4 + 16 = $102.4
