Answer and Explanation:
a. The yield to maturity is
Given that
FV = $1000,
PV = -$900
PMT = 80 (8% of $1,000)
NPER = 30
The formula is
=RATE(NPER,PMT,-PV,FV,TYPE)
after applying the formula, the rate is 8.97%
b. In the case when the bond is sold at par so this means that yield to maturity is equivalent to the coupon rate i.e. 8%
c. The yield to maturity is
Given that
FV = $1000,
PV = -$1100
PMT = 80 (8% of $1,000)
NPER = 30
The formula is
=RATE(NPER,PMT,-PV,FV,TYPE)
after applying the formula, the rate is 7.18%
