    federal loan amount = $29,000

    private loan amount = $14,000

    Step-by-step explanation:

    Total amount is 43000

    Let amount in federal be f

    and

    amount in private be 43,000 - f

    Interest rate at federal is 0.045

    Interest rate at private is 0.02

    THus, we can form the equation shown below and solve:

    f (0.045) + (43,000 - f) (0.02) = 1585

    0.045f + 860 - 0.02f = 1585

    0.025f = 725

    f = 29,000

    and on private = 43,000 - 29,000 = 14,000

    Hence

    federal loan amount = $29,000

    private loan amount = $14,000
