A $$600000$ bond pays interest at j$4=7\%$ redeemable at $100$ in $25$ years. Nancy buys the bond to yield j$4=14\%$ and strips the coupons to sell the remaining strip bond to Cindy, who yields j$4=5\%.$ If Nancy then sells the coupons to Jade, who wishes to yield j$4=4\%,$ What is Nancy's total profit achieved from her investment?
