You and your family go to dinner at a local restaurant in Rexburg, Idaho and your online banking report shows that the total dinner bill (food, tax, and tip) was for $42. Suppose that you did not keep your receipt, but you remember you paid a 20% tip for the service.

Answer 1

To calculate the bill (food and tax) prior to calculating the tip, we can use the following equation:

bill (food and tax) = total bill (food, tax, and tip) / 1.2

We know that the total bill was $42 and the tip was 20%, so we can substitute those values into the equation:

bill (food and tax) = 42 / 1.2

To solve for bill (food and tax), we divide 42 by 1.2:

bill (food and tax) = $35

So the bill (food and tax) prior to calculating the tip was $35.
