If you have a bill of $60 and wish to leave a 20% tip, how much do you leave as a tip?

To calculate a 20% tip on a $60 bill, you first need to determine what 20% of $60 is. You can do this by converting the percentage to a decimal. In mathematical terms, 20% can be expressed as 0.20. To find 20% of $60, you multiply $60 by 0.20:

[

60 \times 0.20 = 12

]

This means that the amount to leave as a tip is $12.

This understanding confirms that the correct answer is indeed $12. The other choices provided do not equate to 20% of the $60 bill, indicating they are equivalent to different percentage calculations or amounts. It's crucial to perform the multiplication correctly and to ensure the percentage is converted properly to reach the accurate tip amount.
