Answer provided by our tutors
Let 'x' represent the cost per share that Michael purchased and let 'y' represent the number of shares Michael purchased. If he had purchased stocks costing x-4 shares for y+6 shares then it would also have cost 1530 dollars:
xy=1530
(x-4)(y+6)=1530

x=34
y=45
So Michael had purchased 34 shares at 45 dollars per share.
