Answer:
it should call back the bonds as it will save $8.25
Explanation:
Bond Price can be calculated using PV function. After 3 years,
N = 2, PMT = 5% x 1000 = 50, FV = 1000, I/Y = 2%
=> Compute PV = $1,058.25
Without the call option, the bond would be worth $1,058.25. But the firm can buy those bonds at $1,050.
Hence, it should call back the bonds as it will save $8.25
