OK, I am totally stupid when it comes to math. I see numbers and I freeze up. I am taking math right now. Something that should be easy as it is nothing but adding, subtracting, multiplying and some division.

Right now I am four assignments behind. I am trying to catch up and am almost there. Until I ran across this problem:

A discount store offers all its merchandise at 25% off the manufacturers' list price. When merchandise has been in the store one month, it is reduced by 15% of the fist discounted price. When it has been in the store two months, it is reduced by 20% off the second discounted price. Use an item with the list price of $100 to show that the discount after two months in the store is not equal to a 60% (the sum of 25%, 15%, and 20%) discount. Explain your results.


I know that this problem is going to seem simple to a lot of you, but as for me, I sit here and scratch my head.

$100 x 25% = first discount
subtract from $100

first discounted price x 15% = second discount
subtract from first discounted price

second discounted price x 20% = third discount
subtract from second discounted price

You will come up with a totally different answer that if you add 25% + 15% + 20% and then multiply it by $100.

100 - 25% = 75

75 - 15% = 63.75

63.75 - 20% = 51.00

therefore discount is:

100 - 51.00 = 49.00

49.00/100 = 49%*

*after correction to division error

Right now I am four assignments behind. I am trying to catch up and am almost there. Until I ran across this problem:

After two months, the price is $51.00 dollars. If it were a 60% discount, the final price would would only be $40. drinker Jasmin was close :tongue:

edit: nevermind; she fixed it!

$100*0.75*0.85*0.8= $51.00

Sorry, that's how I parse it in my head.
