Return-On-Investment Question

Question

if you buy 20 shares of Joe's Pizza for $10 a share, your investment cost is $200. If you sell those shares for $250, then your ROI is ($250-200)/$200 for a total of 0.25 or 25%. This can be confirmed by taking the cost of $200 and multiplying by 1.25, yielding $250.

 

So for instance, we will say the current share is at $9, if I were to purchase 30 shares, my investment is $270. If I am then able to sell those shares for $15 dollars, what will be my ROI?

 

 

So far, I have (320-270)/270=0.185 

Answer 1

15 * 30 = 450

 

(450 - 270) / 270 = 180 / 270 = .667 = 67 %
