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 15% tip on the pre-tax amount. what is the total cost of the meal?

The total cost of the Hu's family meal would be $71.37

Step-by-step explanation:

($58 + 15%) + 7% = 71.37

($58 + 15%) = $66.70

$66.70 + 7% = $71.37

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
