Computing the Commission On a Penny Stock Transaction is a website that executes stock transactions at a flat rate of $7 per transaction; however, the commission (i.e. transaction fee) is higher when trading a penny stock. The following was copied from the trading webpage.

   If the price is under $1 at the time of execution, 
   commission is $7 + 1/2% of the principal.

Note: A penny stock is priced under a dollar.

  1. No or Yes: 1/2% means one divided-by 2%.

  2. Edith Foogooman wants to buy 500 shares of IPT (iParty Corp.) at $0.44 per share. Edith will pay a commission of $_______. [round to nearest cent]

  3. The commission on a penny stock trade is $7 plus one-half percent of the principal amount. Write a symbolic rule that expresses this cost function.
