Question

The Hu family goes out for lunch, and the price of the meal is $43. The sales tax on the meal is 7%, and the family also leaves a 15% tip on the pre-tax amount. What is the total cost of the meal?

Answer 1

to calculate a 7% sales tax on a meal, multiply (7/100) * the meal price (43)
similar logic with the 15% tip on the pre-tax amount

add these two quantities to the original meal price
