4.3.4 Tax and Tips

A meal costs $50. If the sales tax is 8% and you want to leave a 15% tip on the pre-tax amount, what is the total cost of the meal?

• $58.00

• $61.00

• $64.50

• $66.00

Answer explanation

The meal costs $50. Sales tax is 8% of $50, which is $4. The tip is 15% of $50, which is $7.50. Total cost = $50 + $4 + $7.50 = $61.50. Correct total cost is $64.50 after including the tax and tip.
