10. Assume that you wish to invest $200 in a security on a monthly basis and the current market price of the security is $15. Assume also that the price of the security changes by $2.00 every month. Construct two scenarios, one for a rising and another for a falling market, for the next 6 months using the dollar-cost averaging technique. Compute also the total number of shares purchased (allow for fractional shares) and the total values in each scenario.
