Question

The Hu family goes out for lunch, and the price of the meal is $58. The sales tax on the meal is 7%, and the family also leaves a 20% tip on the pre-tax amount. What is the total cost of the meal?

Answer 1

The total price would be $73.66. If you can't tell, I determined the sales tax and tip by making the percent into a decimal (20% is 0.20, 7% 0.07, etc) and multiplied each onw by the original price, then added my tax and tip to the original price.
