An increase/decrease in profit |

Thanikasalam pose la question : It is understood that increase/decrease in profit for current year compared to the previous year is done by the formula (x-y)/y, with x=profit on current year and y=profit on previous year. How do we derive this formula?

= x/y - y/y
= x/y - 1

Price increases and decreases |
2009-09-02 |
|
craig pose la question : I work for an industry that bases it price increases and decreases on commodity pricing - Customer get confused on how/why we calculated new prices due to movement in the market -
Price go up x% for every $10 of movement in the market -
For this example-
Movement went down by $30 and it is 2% for every $10 - so price decrease was 6%.
Customer's price is currently $100.
We say - $100/1.06= new price of $94.3
Customer says - $100*.94= new price of $94.
They don't understand that if board went back up $30 which would be 6% increase, they wouldn't be back at $100 if they multiplied on the price decrease.
$94*1.06=$99.64 vs. $94.3*1.06=$100 (Back to the original price)
What is the best way to explain to customer besides using this example?
Any help or info is appreciated.

$65.09 is 70% greater than the average price |
2009-04-11 |

Kelly pose la question : Hello!
I know you might be thinking that I didn't look through your previous answers, but I really did.
Here's my dilemma- I have a percent increase equation that is missing the 'old" value.
I know that $65.09 is 70% greater than the average price, but I do not know the average price. How do I go about finding that?
I tried to set up an equation, but its throwing me off because the unknown variable is in there twice, and it's been a long time since I've taken math

A 40% markup |
2003-06-12 |

Nick pose la question : I am attempting to determine the Retail price of an item that costs me 11.00. Our company wants to sell it at a markup of 40%. I calculated this two ways, first the way I thought it should be done. Second, the way the calculator does it (and my accountant).
- Cost + Cost*(percentmarkup/100)= retail price 11.00 + 11.00*.40 = retail price 11.00 + 4.40 = 15.40 retail price
- Using the calculators Mark Up key the answer is 18.33. Or 7.33 more than the cost or 67%.
I am confused by this Mark Up key and how it calculates. I used a cost of $10.00 and marked it up 50%. I thought it should equal $15.00 but the calculator says $20.00? This seems to be 100% markup, yes? Can you explain the difference between the way I did it and the way a Business calculator does it? Penny Nom lui répond. |
