Youre working at a restaurant and are left a 7 tip You know

You\'re working at a restaurant and are left a $7 tip. You know this was 20% of the total check. What was the total check? *What equation can represent this situation?*

Solution

Percentage is anything per 100 expressed in % symbol.

Formula:

x% of y = m

i.e. [x/100]*y = m

We have given m= 7 and x=20 solve for y

=> [20/100]*y = 7

=> y = 700/20

=> y = 35

Total check is $35
