  • word problem -

    second part --- x
    first part ---- 3x
    third part --- (93000 - x - 3x) = 93000 - 4x

    .08(3x) + .06x + .09(93000-4x) = 7110
    .24x + .06x + 8370 - .36x = 7110
    -.06x = -1260
    x = -1260/-.06 = 21000

    second investment = x = $21000
    first investment = 3x = $63000
    third investment = 93000-4x = $9000


    check:
    63000(.08) + 21000(.06) + 9000(.09) = 7110

  • what is the interest on $3,400.00 per year -
