Answer:
5.8%
Explanation:
Current yield = 6.1%
Face value of bond = $500
Market price of bond = $475
Let the original coupon rate be CR


Multiply both sides by 475

Cancel out the 475's from the top and bottom of the right side


Flip the sides

Divide both sides by 5000

Cancel out 50000 from the top and bottom of the left side
%
CR = 0.0579 * 100 [convert decimal into a percentage]
CR = 5.79 %
CR = 5.8% [rounded off to the tenth place]
