An investor has accumulated $$7,750$ and is looking for the best rate of return that can be earned over the next year. A bank savings account will pay $8\%.$ A one$-$year bank certificate of deposit will pay $10\%,$ but the minimum investment is $$10,750.$

Required:

a$.$ Calculate the amount of return the investor would earn if the $$7,750$ were invested for one year at $8\%.$

b$.$ Calculate the net amount of return the investor would earn if $$3,000$ were borrowed at a cost of $18\%,$ and then $$10,750$ were invested for one year at $10\%.$

c$.$ Calculate the net rate of return on the investment of $$7,750$ if the investor accepts the strategy of part $b.$ Note: Round your answer to $2$ decimal places.
