Question

At the restaurant, the cost of the meal before tax was

$40. The tax is 8.5%, and Sheri wants to leave at least
an 18% tip. Explain how to approximate the total cost of
the meal.

Answer 1

Explanation:

40x0.085=3.4

40+3.4= 43.4

43.4x0.18=7.8

43.4+7.8=51.212$

Answer 2

This comes out to around 25 percent. Simply multiply 40 by 1/4 to get 10 dollars.
