Compute the present value of interest tax shields generated by these three debt issues. Consider corporate taxes only. Assume that the marginal tax rate is T_c = 0.30. a. A $2,900, one-year loan at 7%. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

b. A three-year loan of $2,900 at 7%. Assume no principal is repaid until maturity. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

c. A $2,900 perpetuity at 6%. Figure the present value.
