The first thing we should do is to multiply 50 and 13 3/4 13 3/4 is equivalent to 13.75 . So, we then multiply 50 x 13.75 and we get 687.50. so, $687.50 was the amount spent on the stock. Now, lets find out how much they sold them for: What we do is multiply 12 and 50 50 x 12 would be 600 We can find out the loss by subtracting $687.50 - $600 and that gives us $ 87.50. Therefore, $87.50 is your answer :)
