An investor has accumulated $$5,450$ and is looking for the best rate of return that can be earned over the next year. A bank savings account will pay $7\%.$ A one$-$year bank certificate of deposit will pay $9\%,$ but the minimum investment is $$8,450.$

Required:

a$.$ Calculate the amount of return the investor would earn if the $$5,450$ were invested for one year at $7\%.$

b$.$ Calculate the net amount of return the investor would earn if $$3,000$ were borrowed at a cost of $17\%,$ and then $$8,450$ were invested for one year at $9\%.$

c$.$ Calculate the net rate of return on the investment of $$5,450$ if the investor accepts the strategy of part $b.$

Note: Round your answer to $2$ decimal places.
