An investor purchased shares of stock at a certain price. If the price of each share increases by $4.25 and the total value is $212.50, how many shares were purchased?
a.
100
b.
60
c.
425
d.
50


Solution:

Let a be the number of shares of stock, the investor purchased.

The price of each share is increased by $4.25.

The total price of stock is increased by $212.50.

Number of shares × increase in price of each share = Increase in total price of the stock.

a × 4.25 = 212.50
[Substitute the values.]

a = 212.504.25=50
[Divide each side by 4.25 and simplify.]

So, the investor purchased 50 shares of stock.
