Answer:
the bill before for the lunch before the tip was $13.75
Step-by-step explanation:
Let bill before for the lunch before the tip was $x.
Now, it has been given that Mrs. chin paid a 20 percent tip on the bill for lunch.
Hence, the equation for the situation is
\(0.20x=2.75\)
Now, solve the equation for x
Divide both sides by 0.20
\(x=\frac{2.75}{0.20}\\\\x=13.75\)
Hence, the bill before for the lunch before the tip was $13.75
