JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake?
To find the tip, you need to know what 15% of $8 is. That is done by multiplying 15% and the total of JJ’s meal. Change the percent to a decimal by moving the decimal point, two places to the left.
