Mr. Jones has $ 9 comma 000 to invest in three types of stocks, low-risk, medium-risk, and high-risk. He invests according to three principles. The amount invested in low-risk stocks will be at most $ 5 comma 000 more than the amount invested in medium-risk stocks. At least $ 7 comma 000 will be invested in low- and medium-risk stocks. No more than $ 6 comma 000 will be invested in medium- and high-risk stocks. The expected yields are 6% for low-risk stocks, 7% for medium-risk stocks, and 8% for high-risk stocks. How much money should Mr. Jones invest in each type of stock to maximize his total expected yield?
