A stockbroker placed the following order for a customer:


• 50 shares of Kaiser Aluminum preferred at $100 a share
• 100 shares of GTE preferred at $27.20 a share
• 20 shares of Boston Edison preferred at $12.20 a share

What is the weighted arithmetic mean price per share?
$99.50
$46.85
$67.19
$27.20

(50*100 + 100*27.20+ 20*12.20)/(50+ 100+20) =

$7964/170
= $46.85

(50*100 + 100*27.20+ 20*12.20)/(50+ 100+20) =

$7964/170
= $46.85

To find the weighted arithmetic mean price per share, you need to multiply the number of shares of each stock by its corresponding price per share. Then, sum up the results and divide by the total number of shares.

Let's calculate it step by step:

1. Multiply the number of shares by the price per share for each stock:
- Kaiser Aluminum preferred: 50 shares * $100 = $5000
- GTE preferred: 100 shares * $27.20 = $2720
- Boston Edison preferred: 20 shares * $12.20 = $244

2. Add up the results from step 1:
$5000 + $2720 + $244 = $7964

3. Calculate the total number of shares:
50 shares + 100 shares + 20 shares = 170 shares

4. Divide the total value of the shares by the total number of shares:
$7964 / 170 shares = $46.85

Therefore, the weighted arithmetic mean price per share is $46.85.

So, the correct answer is $46.85.
