The simple interest оn аn investment is directly prоpоrtionаl to the аmount of the investment. By investing $6700 in a municipal bond, you obtained an interest payment of $251.25 after 1 year. Find a mathematical model that gives the interest I for this municipal bond after 1 year in terms of the amount invested P. (Round your answer to three decimal places.)
