Question

The tip given to the good service of a restaurant is $40 which is 9% of the total bill. How much was the bill? Explain

Answer 1

`\huge\boxed{\sf \$ \ 444.44}`

Explanation:

Given data:

Tip = $40

This tip was 9% of the total bill.

Let the total bill be x.

So,

9% of x = 40

Key: "of" means "to multiply", "%" means "out of 100"

So,

`\displaystyle (9)/(100) * x = 40\\\\0.09 * x =40\\\\Divide \ both \ sides \ by \ 0.09\\\\x = 40/0.09\\\\x = \$ \ 444.44\\\\\rule[225]{225}{2}`
