    Hi <3

    The question is...

    "Myron decides to buy a stock for $9 a share. Myron sees his stock skyrocket to $80 before he sells it. If he sells the stock for $80, what percent did his stock increase by?"


    a) 720%
    b) 840%
    c) 800%
    d) 889%
    e) 900%


    Thank you soooo much.
    Wish you all thee very best!

    (80-9)/9 * 100%
    = 789%

    How did you know to subtract (80-9)?

    I would've just done 9(x%)=80...

    Instead of what you did. Haha :( The correct answer is 800%

    Correct answer would have been 800% if the final price was 81 instead of 80.

    Original price: $9
    Stock price: $18 = 100% increase
    Stock price: $27 = 200% increase
    Stock price: $36 = 300% increase
    Stock price: $45 = 400% increase
    Stock price: $54 = 500% increase
    Stock price: $63 = 600% increase
    Stock price: $72 = 700% increase
    Stock price: $81 = 800% increase
