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

Click For 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.
 
The working out suggests first equating ## \sqrt{i} = x + iy ## and suggests that squaring and equating real and imaginary parts of both sides results in ## \sqrt{i} = \pm (1+i)/ \sqrt{2} ## Squaring both sides results in: $$ i = (x + iy)^2 $$ $$ i = x^2 + 2ixy -y^2 $$ equating real parts gives $$ x^2 - y^2 = 0 $$ $$ (x+y)(x-y) = 0 $$ $$ x = \pm y $$ equating imaginary parts gives: $$ i = 2ixy $$ $$ 2xy = 1 $$ I'm not really sure how to proceed from here.
