1.how much did you spend? spent=shares time cost per share=300*6.31=1893how much did you sell for? sold=shares times cost per share=300*8.24=2472money made=sell-spent=2472-1893=579you made $5792. same as before but now you need to calculate number of sharesinvested=cost per share times number of shares5200=10 times number of sharesdivide by 10 both sides520=number of sharesthen you sold at 7.8520*7.8=4056loss=invest-sell=5200-4056=1144you lost $1144
