8. Lesson 2.2: Money & Change

9. Examples; money & change
Use the prices to the left. Kyle wants to buy a pound of grapes, a package of cereal, and a loaf of bread. How much will that cost him?
= Grapes + Cereal + Bread
= ($1.99) + ($3.57) + ($0.89)
= $6.45

10. Examples; money & change
Use the prices to the left. Kim wants to buy a two loaves of bread, a two jars of pickles, one and a half pounds of ham, and a pound of cheese. How much will that cost her?
= 2 (Bread) + 2 (Pickles) (Ham) +1 (Cheese)
= 2($0.89) + 2($4.39) + 1.5($5.09) + ($6.39)
= ($1.78) + ($8.78) + ($7.64) + ($6.39)
= $24.59

11. Examples; money & change
Use the prices to the left. Cory purchased one package of lunch meat and one pound of chicken. How much change will he receive if he handed the cashier $10.00?
= 1 (Lunch Meat) + 1 (Chicken)
= ($3.79) + ($2.19)
= $5.98
Change = (Amount Given )– (Price)
= ($10.00) + ($5.98)
= $4.02

12. Examples; money & change
Use the prices to the left. Carrie purchased two cans of soup, 2 dozen eggs, and a gallon of milk. How much change will he receive if she handed the cashier $20.00?
= 2(Soup) + 2(Eggs) + 1(milk)
= 2($4.49) + 2($1.39) + ($2.37)
= ($8.98) + ($2.78) + ($2.37)
= $14.13
Change = (Amount Given )– (Price)
= ($20.00) + ($14.13)
= $5.87

14. Lesson 2.3: Understanding Coupons

15. Vocabulary
Stores offer coupons or rebates or cash refunds to try to get customers to purchase more items.

16. Examples; final price Total = (Computer) + (Program)
You decided to buy a new computer for $ but you have $50 rebate coupon. With that you buy a $75 computer program with a $15 coupon. Find your final price.
Computer = (Cost) - (Coupon)
Computer = ($599) - ($50)
Computer = $549.00
Game = (Cost) - (Coupon)
Game = ($75) - ($15)
Game = $60.00
Total = (Computer) + (Program)
Total = ($549) + ($60)
Total = $609.00

17. Examples; final price ipod = (Cost) - (Coupon)
You have a 30% off coupon and are purchasing an ipod that has a regular price of $349. Find the sale price of the ipod.
ipod = (Cost) - (Coupon)
ipod = ($349) – [(Cost) x (Coupon %)]
ipod = ($349) – ($349)(.0)
ipod = ($349) – ($104.70)
ipod = $244.30

18. Examples; final price Laptop = (Cost) - (Coupon)
You have a 25% off coupon and are purchasing a new laptop that has a regular price of $599. Find the sale price of the laptop.
Laptop = (Cost) - (Coupon)
Laptop = ($599) – [(Cost) x (Coupon %)]
Laptop = ($599) – ($599)(.25)
Laptop = ($599) – ($149.75)
Laptop = $449.25

19. Examples; final price Cost = 2(dinner) – (Coupon)
You have a coupon that offers a savings of $1.50 on any two TV dinners. Each dinner is marked as $4.59. How much will two TV dinners cost with the coupon?
Cost = 2(dinner) – (Coupon)

21. Lesson 2.4: Unit Pricing

22. Vocabulary
Comparison Shopping is a system that allows shoppers to compare the prices of various items easily and quickly

23. Examples; unit price Muffin = (Cost) ÷ (Amount)
You went to the store and bought a 45-ounce can of coffee for $4.99, a 2-liter bottle of soda for 1.29, and a dozen muffins for $5.49. Find the unit price of each purchase.
Coffee = (Cost) ÷ (Amount)
Coffee = ($4.99) ÷ (45)
Coffee = $0.11 per ounce
Soda = (Cost) ÷ (Amount)
Soda = ($1.29) ÷ (2)
Soda = $0.65 per liter
Muffin = (Cost) ÷ (Amount)
Muffin = ($5.49) + (12)
Muffin = $0.46 per muffin

24. Examples; unit price Pop Tart = (Cost) ÷ (Amount)
You went to the store and bought a 24-pack of soda $7.99, a 12-serving box of cereal for $3.59, and a box of pop-tarts (8 pop-tarts) for $2.69. Find the unit price of each purchase.
Soda = (Cost) ÷ (Amount)
Soda = ($7.99) ÷ (12)
Soda = $0.67 per soda
Cereal = (Cost) ÷ (Amount)
Cereal = ($3.59) ÷ (12)
Soda = $0.30 per serving
Pop Tart = (Cost) ÷ (Amount)
Pop Tart = ($2.69) + (8)
Pop Tart = $0.34 per pop tart

25. Examples; best deal
You can buy 12-ounce soda in 12-pack or a 24-pack. Find the best deal if a 24-pack costs $8.29 and a 12-pack is $4.59
Soda (12 pk) = (Cost) ÷ (Amount)
Soda (12 pk) = ($4.59) ÷ (12)
Soda (12 pk) = $0.38 per soda
Soda (24 pk) = (Cost) ÷ (Amount)
Soda (24 pk) = ($8.29) ÷ (24)
Soda (24 pk) = $0.35 per soda
Buying the 24 pack is more cost effective because it costs $0.03 less per soda.

26. Examples; best deal
You can buy oatmeal in different sized packages. An 18-ounce package costs $1.99, a 42-ounce package costs $3.35, and a 112-ounce package costs $6.55. Based on the price find the best deal per ounce.
(18 oz) = (Cost) ÷ (Amount)
(18 oz) = ($1.99) ÷ (18)
(18 oz) = $0.11 per ounce
(42 pk) = (Cost) ÷ (Amount)
(42 pk) = ($3.35) ÷ (42)
(42 pk) = $0.08 per ounce
(112 pk) = (Cost) ÷ (Amount)
(112 pk) = ($6.55) ÷ (112)
(112 pk) = $0.06 per ounce
Buying the 112 ounce package of oatmeal is most cost effective if you like oatmeal.

28. Lesson 2.5: Eating Out

29. Vocabulary
A bill is a piece of paper showing everything that was ordered and the total cost of the meal, including tax.
Split the check means to divide the total amount due, by the number of diners.
Tip is a percentage of a total restaurant bill paid to the server.

30. Examples; eating out Total cost with tip = (Bill) + [(Bill) x (Tip %)]
Dan, Cameron, Jose, Tim, and Jordan enjoy a dinner out. The total bill was $177.81, including tax. Assume they also pay a 15% tip. Find the amount each person should pay.
Total cost with tip = (Bill) + [(Bill) x (Tip %)]
Total cost with tip = ($177.81) + [($177.81) x (.15)]
Total cost with tip = $204.48
Cost per person = (Total Cost) ÷ (# of people)
Cost per person = ($204.48) ÷ (5)
Cost per person = $40.90

31. Examples; eating out Total cost with tip = (Bill) + [(Bill) x (Tip %)]
Joe and three friends went out for lunch. The total bill was $107.76, including tax. Assume they also pay a 15% tip. Find the amount each person should pay.
Total cost with tip = (Bill) + [(Bill) x (Tip %)]
Total cost with tip = ($107.76) + [($107.76) x (.15)]
Total cost with tip = $123.92
Cost per person = (Total Cost) ÷ (# of people)
Cost per person = ($123.92) ÷ (4)
Cost per person = $30.98
