Question

Let's assume that, on a certain date, you bought r total_shares shares in a company, paying price_purchase per share. After some time, you sold r qtd_sell_1 shares for a r price_sell_1 each and the remaining r qtd_sell_2 shares were sold for r price_sell_2 on a later day. Using a script in R, structure this financial problem by creating numeric objects. What is the total gross profit from this sequence of transactions on the stock market?
