A friend's granddaughter has asked me for help on how to figure out a problem and I am stumped. The question is: What is the brokerage fee for 150 shares of stock at 11 1/2 per share? Since this is over 100 shares of stock it would be a round lot and the information for a round lot over $1,000 is that the brokerage fee is $29 + 1.5% of the amount over $1,000. The granddaughter and I both get $39.88, however the answer key says the answer is $53.50. We cannot figure this out. The question also has information for amounts over $100 for both round and odd lots. I've ran the numbers for all of the options and don't get the answer key answer. Any help on how to figure this out would be appreciated.
