Question

While dining at yet another 5 star restaurant, which is my normal, I received the bill for $95.11 which by the way included an automatic 15% p. Because my generosity is my weakness, I wanted to leave a 20% p, instead. How much should I add to the bill to make this happen?

Answer 1

Answer:

$16.54

Step-by-step explanation:

First step we need to do is to find the bill without the 15% tips:

95.11 = 1.15x

x = $82.70 is the original bill

Now we can add the 20% tips and multiply it into the original:

82.70 x 1.2 = $99.24 is the new bill

To find out how much you tipped:

99.24 - 82.7 = $16.54 is your new tip
