What is the Percentage Profit on a House Bought for $500 and Sold for $700?

AI Thread Summary
The house purchased for $500 and sold for $700 yields a profit of $200. The calculation for percentage profit is correct at 40%, derived from the formula (200/500)*100%. The discussion clarifies that the term "profit" is the appropriate terminology, distinguishing it from "prophet," which is unrelated to the topic. Overall, the calculations and terminology have been confirmed as accurate.

The right word is "profit". Prophet is something religious and this we don't discuss on this forum ;).

You can just say the profit is 200$. The question doesn't ask for a percentage. But the percentage is correct if you want it as a percentage.
 
Sorry it's profit

Fixed now.
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
