To comlete the answerFor the solution of $50, the total no.of glassware is 3600/50 = 72
But first the first week it sold 60 , then block 12. The second week still have some glassware to sold . So the total no. of glassware 60 + 12 + something which >72
So the solution of $50 is incorrect.
That means $36 is correct
