Answer:
7.50%
Step-by-step explanation:
The formula to solve this problem is stated below.

where p = price paid = $10,000
A = annual coupon payment = $750
n = tenor = 5 years
F = face value paid at maturity = $10,000
r, the unknown = rate of return.
Using extrapolation, the value of r that resolves the problem = 7.5%. The is expected since the price of the bond is the same as face value. As such, the rate of return was the same as
= 7.5%.
