$156.35

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

`(\$132.50)/(100\%)=(x)/(118\%)\\\\x=132.50(118)/100\\\\x=\$156.35`
