Question

Caroline bought 20 shares of stock at 101/2, and after 10 months the value of the stocks was 111/4. If Caroline were to sell all her shares of this stock, how much profit would she make? A. $15 B. $10 C. $225 D. $210

Answer 1

First,
101.2=10.50
111/4=11.25
Second, we minus our old by the new.
11.25-10.50=0.75
Then, we times the by stock;answer is below.
0.75 * 20 = 15

Answer 2

Answer:

 Option A is correct that is $15.

Step-by-step explanation:

Caroline bought 20 shares of stock at $10\frac{1}{2}=\frac{21}{2}$, and after 10 months the value of the stocks was $11\frac{1}{4}=\frac{45}{4}$.

We need to calculate the profit which is the difference of the two values of the stock.

$\frac{45}{4}-\frac{21}{2}$

$\frac{3}{4}$

The above value is for 1 share we have to calculate it for 20 shares

So, we will multiply it with 20 we get:

$\frac{3}{4}\cdot 20=15$

Therefore, Option A is correct that is $15.
