Explanation:
A rule of thumb used to determine if the monthly rent earned from a piece of investment property will exceed that property's monthly mortgage payment.

P = MC/1+(1/Ed)
Ed is easticity of demand for a firm, not the market. So, Ed = -3.
P = $50/1+ (1/(-3)) = $50/(1-1/3) = 50/(2/3 ) = $75
