Answer 1

Answer:

$156.35

Step-by-step explanation:

we know that

A group of friends went to lunch, and their bill was $132.50

In this problem

$132.50 represent the 100%

100%+18%=118%

so

using proportion

Find out the total amount that represent 118%

Let

x ----> the total amount of the bill

$\frac{\ 132.50}{100\%}=\frac{x}{118\%}\\\\x=132.50(118)/100\\\\x=\ 156.35$
