If you bought a stock last year for $59 and it risen 13% how much is the stock worth now
Rina8888 [55]

Answer:

<h3> $ \underline{ \underline { \sf{ \bold{66.67}}}}</h3>

Step-by-step explanation:

Price of stock bought = $ 59

% rise = 13%

Price of stock rise :

⇒\sf{ \frac{13}{100}  \times 59}

⇒$ \sf{7.67}

New price is 13% more than $ 59

Hence, New price = $ 57 + $ 7.67

= $ 66.67

Hope I helped!

Best regards!!
