1. At dinner Mr. Murphy’s bill came out to $39.99 before tax and tip sales tax is 6% he wants to also have a 20% tip how much money will he end up spending altogether.

2. What’s 15% of 180

Answer :

Add the tips: 6% + 20% = 26%

$39.99 / 100 = 0.399
0.399 x 126 = $50.39

Total = $50.39

2. 180 / 100 = 1.8 (1%)
X 15
= 27

Answer is 27.

By the way a quicker method would be to:
180 x 0.15 = 27

If you understand it.
