Aly is a real estate professional representing a client who is interested in purchasing a neighbourhood strip mall. The property is being offered for sale at $$5,000,000.$ The client plans on selling the property at the end of $5$ years for $$5,500,000.$ Aly projects the annual net operating income to be $$250,000$ for the first year, $$250,000$ for the second year, $$260,000$ for the third year, $$260,000$ for the fourth year, and $$250,000$ in the fifth year. Based on Aly's projections, what is the annual return the client can expect if they decide to purchase the property?

This question has been posted before and has been answered. But I need to know how to do this calculation on the HP$10$bII$+$ financial calculator. Please help!
