THE MALL.
Go On
2Problem 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
3What should I do?
OR
14.95
19.95
Click on the shoe you would buy.
4I 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
5Thinking 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.

8Sales 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.

9Sales 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

12I 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.

14Tips!!!!
- 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.

15Tips 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.
Go ON
16Tips 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
