Question 3

Theatre Revenues 
A financier whose specialty is investing in stage productions has observed that,in general,movies with "big-name" stars seem to generate more revenue than those plays whose stars are less well known.To examine his belief he records the gross revenue and the payment (in $ millions)given to the two highest-paid performers in the play for ten recently staged plays.   ​ ​
-{Theatre Revenues Narrative} Estimate the gross revenue of a play if the two highest paid performers received 6 million dollars.

Accepted Answer

The answer of  Theatre Revenues 
A financier whose specialty...
