Answer:
8.8%
Explanation:
The fomula to calculate the yield to maturity is:
YTM= (C+((FV-PV)/t))/((FV+PV)/2)
C= Coupon
FV= Face value
PV= Present value
t= time to reach maturity
YTM= (100+((1,000-1,080)/10))/((1,000+1,080)/2)
YTM= (100+(-8))/1,040
YTM= 92/1,040
YTM= 0,088* 100= 8.8%
Their yield to maturity (YTM) is 8.8%
