A markup of 30% 2008-12-06
Tammy pose la question :
How can a markup of 30% be calculated by using 1.43 times the original cost? Where does the 1.43 come from? For example: the original cost is 830.00 the markup is 30 %. The selling cost is 1186.90. My boss uses 1.43 to figure the mark up for 30% and 1.23 for 25% and 1.1 for 10%. What I want to know is how do they come up with these figures?

What is the pre GST price? 2008-12-05
Chris pose la question :
I've been looking at a few answers to the question of before and after GST price calculation. the suggestion have been :: multiply the pre GST price by 1.10 to get the price and reverse to get a pre GST price.

But how do you calculate the pre GST price from an existing retail price?

For example if you take an item that is $150.00 and multiply it by 0.10 you get $15.00 as the GST add on. Apparently giving you $135.00 as the pre GST price. However if you then multiply $135.00 by 1.10 you get the $148.50 as the total.

So the question is how does one calculate the real pre GST price from an existing retail price?

Regards,

Chris

The volume of a yogurt pot 2008-12-04
Robyn pose la question :
Okay, I know you have some answers on converting this already, but I can not convert the yoghurt pot I need yet into ml. Is there some way to explain this using the yoghurt as an example? The pot's 150g of lowfat strawberry yoghurt... would the 'low-fat' have an effect on this? I'm sorry if this is a bother for you to answer, I just don't seem to be able to get it... Have a nice day. - Robyn

Some number theoretic speculations 2008-12-04
Andrew pose la question :
Another way of looking at the 'alternating parity polynomial', again based on Fermat's Little Theorem, is to substitute (a - b) for x in x^(p-1) - 1 as this is always divisible by any prime p. So, if one removes the "- 1", there is always a remainder of (1/p)! (I took up your challenge!)
