Answer: the number of stocks that he owned is 500
Step-by-step explanation:
Let x represent the number of shares of stock he owned.
On a particular day, the price of one share of a video gaming company's stock dropped by $1.20. This means that the amount that was lost by the share holder is - $1.2x because loss is negative
If the stockholder lost $600 that day, the expression would be
- 1.2x = - 600
x = - 600/ - 1.2
x = 500
