Answer:
The increase in point's in stock are:
12 points.
Step-by-step explanation:
The price of a share of Arbor's stock increased from 24 1/2 to 36 1/2.
i.e. initial stocks were= 24 1/2
it is given in mixed fraction we will change this to improper fraction as:
[tex]24\dfrac{1}{2}=\dfrac{24\times 2+1}{2}\\\\24\dfrac{1}{2}=\dfrac{49}{2}[/tex]
similarly the changed value of stocks is:36 1/2
On changing this mixed fraction value to improper fraction we get:
[tex]36\dfrac{1}{2}=\dfrac{36\times 2+1}{2}\\\\36\dfrac{1}{2}=\dfrac{73}{2}[/tex]
Now, the change in the stock's value is:
[tex]\dfrac{73}{2}-\dfrac{49}{2}\\\\=\dfrac{73-49}{2}\\\\=\dfrac{24}{2}\\\\=12[/tex]
Hence, the stock's increased by:
12 points.
