Joplin and Hannah need to figure out how much their total bill will be including the tip. If the meal was $22 and they are leaving a 15% tip, which equation should they use to determine the total cost including tip.

• $22 + $1.30

• $22 + 13.00

• $22 + $3.30

• They should just stiff the waitress because it's way too hard to compute a 15% tip and add it on to the cost of the meal.

Frank and Mason have smart mothers, so they knew they needed to find 20% of 80 by turning 20% into the decimal .2 and multiplying it by $80. They did this and found that the tip would have to be $16. How much is the total cost of the meal including the tip?

• 80 + 1600 = $1680

• 80 + 16 = $96

• 80 + 1.6 = 81.60

• They should all just run from the restaurant and hope they don't get caught by the cops!!
