Hector runs a one-product widget shop. Each month, his fixed costs, whether he produces anything or not, amount to x dollars. The marginal cost of producing and selling one widget is a constant y dollars, regardless of the number he produces. He generally can sell widgets for q dollars each. What is the minimum number of widgets he must produce, assuming he sells every widget he produces, to break even (neither make a profit nor incur a loss) in a given month?	Answers.
A) x/(y - q)
B) x/(q - y)
C) x
D) x/q
E) x/y
Two ways...   1) let t be the total number, so cost = t*y+x and selling price=t*q..   No profit no loss....t*y+x=t*q.....T=x/(q-y)...   x/(q - y)
