3. Marilyn purchased 400 shares of stock for $22.75 per
Mazyrski [523]

The percent gain is 52.1%

Step-by-step explanation:

Given

Purchase price of one share = $22.75

Sale price of one share = $34.60

Total shares = 400

So,

Total purchase price of shares = 22.75*400 = $9100

Total sale price of shares = 34.60*400 = $13840

Total capital gain:

= Sale\ price - Purchase\ price\\= 13840 - 9100\\=4740

Percent capital gain is given by:

Capital\ gain = \frac{Capital\ gain}{Purchase\ price} * 100\\= \frac{4740}{9100} * 100\\=0.5208*100\\=52.08

Rounding off to nearest tenth

52.1%

Hence,

The percent gain is 52.1%
