Question

Tiffany and her friends are having lunch at Russell's Diner. The total cost of their lunch

including tax, is $54.63. Tiffany and her friends have $65.00 altogether and want to leave
a tip equal to 15% of the total bill. Is $65 enough to cover the cost of their lunch and the
15% tip for the server?

Answer 1

Yes!

Explanation:

If we want to find out if they have enough to pay for the meal and tip then we need to do 115% of 54.63

`1.15*54.63=62.8245`

Since this is money we are talking about we need to round to the nearest hundredths place

`62.82`

Since the bill with tax plus the tip is only $62.82 and they have $65 then they can afford to tip 15% and pay for the meal.
