Question

Mr. and Mrs. Smith go out for lunch at a local restaurant. Their bill is $32.75, and they want to leave a 20% tip. If they pay with a $50 bill, how much changewill they get back?

Answer 1

First, let's calculate the tip:

Express the percentage as a decimal:

20% = 20/100 = 0.2

Multiply the previous result by the bill:

$Tip\colon32.75\times0.2=6.55$

Therefore, the bill plus the tip is:

$6.55+32.75=39.3$

The change will be:

$50 - $39.3 = $10.7
