Question what is the difference between Discount and Sale Price?

Discount is what you save, and sale price is what you pay.

How do you calculate these two amounts?

*example question -*You get a 50% discount on a $30.00 pair of shoes....

DISCOUNT- .50 x 30.00 = 15.00.... $15.00 is your discount

SALE PRICE- 30.00 - 15.00 (discount) = 15.00.... $15.00 is also your sale price

How do you calculate mentally percentages without going insane?

you should take a happy number first and start from there, then work your way through....for example:

What is 50% of 70?

you should already know the answer to this one.....70 divided by 2 equals 35...

it's that simple!

What is 35% of 80?

now here you have to use the happy number stradegy (or as i would call it anyways)

firstly you go take an easy number to work with...maybe 25%

25% of 80 is 20

now you go: 35 - 25 = 10

and so now you must find 10% of 80....which should be 8

and now you should add 20 and 8 which should equal 28

your answer to this solution is 28

hmmm..well i didn't go insane on that, that's my way of figuring this out =)
