On February 2, 2016, an investor held some Province of Ontario stripped coupons in a self-administered RRSP at ScotiaMcLeod, an investment dealer.

Suppose that on February 2, 2017, the security's price was $89.00. If an investor had purchased it for $84.73 a year earlier and sold it on this day, what annual rate of return would she have earned? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Annual rate of return 7% c. If an investor had purchased the security at the market price of $89.00 on February 2, 2017, and held it until it matured, what annual rate of return would she have earned? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Annual rate of return %
