Lowell Corporation recenty issued $10-$year bonds at a price of $$1,000$ with a $8$ percent semi$-$annual coupon at par. Now it wishes to issue new $10$ year bonds with $2$ percent semi$-$annual coupon with a face value of $$1,000.$ If both bonds have the same yield$-$to$-$maturity, how many new bonds must Lowell issue to raise $$4,000,000$cash?
