Milt Corporation owns and operates two facilities that manufacture paper products. One of facilities is situated in State D, and other is located in State E. Milt prepare $1,200,000 of taxable income, comprised of $1,000,000 of income from its manufacturing facilities and a $200,000 gain from sale of non-business property located in E. E does not distinguish between business and non-business property. D apportions business income. Milt's activities within two states are outlined below.
