You can put this solution on YOUR website!
Let x = the cost of the bill before the tip


21% of the bill is the same as 0.21x


Add this to the bill to get x+0.21x = 1.21x


So the total bill (meal+tip) is 1.21x and this is equal to 52.03. Set the two equal and solve for x


1.21x = 52.03


x = 52.03/1.21


x = 43


The original bill (without tip) is $43
