Question

Alberto is a waiter. He waits on a table of 4 whose bill comes to $110.05. If Alberto receives a 15% tip, about how much will he receive?

Answer 1

If the total bill comes to $110.05, we know that we are going to have to take 15% of this for his tip.

So we convert 15% to a decimal by dividing by 100:

$\frac{15}{100}=0.15$

Then we multiply this by the amount of the bill:

$110.05*0.15=16.5075$

So if we round this to the nearest cent, we get $16.51.

Therefore, Alberto's tip will be about $16.51.
