The hu family goes out for lunch and the price of the meal is $45 the sales tax on the meals is 6% and the family also leaves a 20% tip on the pretax amount what is the total cost of the meal

45 *.06 = 2.7

45 *.2 = 9

45+2.7+9 = 56.7

The total cost will be 56.70 because first you find out the sales tax and you get 2.70 and then you find the tip and you get 9. if you add 9 and 2.70 you get 11.70 which you add to 45 and get your answer of 56.70
