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?

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.

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21
