Two months ago, Qasim purchased a bond for $$4,000.$ Initially, he calculated the bond would be equivalent to a five$-$month simple interest loan with an interest rate of $4\mathrm{.}7\%$ per year. However, Qasim's car unexpectedly broke down today. To pay for the car repair, he decided to sell the bond to a friend for $$4,010.$
