• 1.5 x 22

Joplin and Hannah go out to lunch and spend $22.00 on their meal. Their waitress is really nice, so they want to leave her a 15% tip. How much is the total cost of the meal including the tip.

• $253

• $23.00

• $2.20

• $25.30

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 take their mothers out for dinner. They go to a swanky restaurant and the meal costs $80! They don't have enough money so their mothers will have to pay for the 20% tip. How can their mother's compute the amount of the tip?

• tip = 20 x 80 or $1600

• tip = 2 x 80 or $160

• tip = .2 x 80 or $16

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!!

Harder Question: Chelsea and Mary go out for lunch and spend $14.40 including the 20% tip. What equation should you use to find the cost of the meal BEFORE tax? c = cost before tip

• t = .20 x 14.40

• 14.40 = 1.2c

• 14.40 = .20c

What is the percent equation?

• percent = decimal x whole

• part = percent (as a decimal) x whole

• whole = part x percent

How much tax will Cael have to pay for the $14 DVD is the sales tax rate is 8%.

• 8 x 14 = 112 He will pay $112 for tax

• .8 x 14 = 11.20 He will pay $11.20 for tax.

• .08 x 14 = 1.12 He will pay $1.12 for tax

• I don't know how to find a percent of a number because I don't pay attention or do my assignments in math.

Trey buys a new coat for $65 and the sales tax is 9%. Which equation should Trey use to figure out the amount of tax he will pay?

• tax = .09 x 65

• $16.32
