THE MALL.
Go On
2
Problem 1 Buying shoes
  • I found the coolest shoes. They were 19.95.
  • I also found a pair for 14.95 that were OK.
  • I had 20.00 cash
  • I had to decide which to buy.

19.95
OR
14.95
Go On
3
What should I do?
OR
14.95
19.95
Click on the shoe you would buy.
4
I took the 19.95 shoes up to the counter.
  • The cashier said, That will be 21.45
  • Shoot, I forgot about the sales tax!
  • I ran out of the store embarrassed.

Go On
5
Thinking about the sales tax ,I knew I could only
afford to buy the 14.95 shoes or wait to save up
more money and buy the others later.
  • But I wanted shoes today!
  • I went to the counter and paid 16.15 including
    tax and happily left the store.

Sales Tax
  • Sales tax is an additional charge on purchases
    made imposed by the government.
  • There are different rates of sales tax for food
    and nonfood items. Also the tax varies from state
    to state.

Sales Tax part 2
  • You need to know how to convert percents to
    decimals in order to multiply.
  • For example the 19.95 shoes will have a 7.5
    sales tax in California. So I would multiply
    19.95 by .075 ( the decimal conversion of 7.5)
  • The answer 1.49625 would be 1.50 to the closest
    cent.I would add this to the price of the shoes
    for a grand total of 21.45

Problem 2The Restaurant
  • We went to sit down and eat.
  • The food was great, and our waiter was very nice
  • The waiter brought our check.
  • We got up to leave.
  • My friend told me to leave a tip.
  • What is a tip?I didnt know.

Go ON
11
What should I do?
Ask my friend what a tip is and leave a tip.
Just say Ok, ignore him, and leave.

I asked my friend what a tip was
  • He said that it is a percentage of the price of
    the meal . Usually 15. You give it to the waiter
    or waitress to say thank you for the good
    service.
  • I left a 20 tip since our
    waiter was so nice.
    He thanked us as we left.

Tips!!!!
  • A tip, or gratuity, is a small amount of money
    given voluntarily as a token of appreciation for
    a service rendered. According to Webster's
    Dictionary, the word "tip" is also considered by
    many to be an acronym T.I.P. - "To Insure
    Promptness" or "To Insure Prompt" service. We tip
    our servers as a way of thanking them for good
    service. We might also leave a very low tip, or
    no tip at all, as a signal that the service was
    terrible.

Tips part 2
  • Most of us know that we should tip waiters at
    restaurants 15 to 20 of the bill.
  • It's also important to note that restaurant
    servers pay taxes on 8 to 10 of their total
    receipts, not the actual amount of tips they
    earn. If you don't tip them, they are actually
    losing money because they're paying taxes based
    on the amount of your meal.

16
Tips part 3
  • You need to know how to change percents to
    decimals in order to multiply.
  • For a 15 tip multiply the amount of your bill by
    .15
  • Example 30.00
  • x . 15
  • 4.50 would be your 15 tip
