Answer:
824.28
Explanation:
Market price of a bond is the total sum of discounted coupon cashflow and par value at maturity. This is a 4-year bond with semi-annual payment so there will be 8 coupon payment in total. Let formulate the bond price as below:
Bond price = [(Coupon rate/2) x Par]/(1 + Required return/2) + [(Coupon rate/2) x Par]/(1 + Required return/2)^2 + ... + [(Coupon rate/2) x Par + Par]/(1 + Required return/2)^8
Putting all the number together, we have
Bond price = [(4.5%) x 1000]/(1 + 7.5%) + [(4.5%) x 1000]/(1 + 7.5%)^2 + ... + [(4.5%) x 1000 + 1000]/(1 + 7.5%)^8
= 824.28
