Woodland Developers purchases land for $1.5 million that it will subdivide into 400 lots. These lots are of different sizes and shapes but can be roughly sorted into three groups graded A, B, and C. As Woodland sells the lots, it apportions the purchase cost of $1.5 million among the lots sold and the lots remaining on hand. Instructions: What is the cost allocated to grade C lots, assuming that grade A estimated sales value $1,000,000, grade B estimated sales value $900,000, and grade C estimated sales value $600,000? (Please write your answer without commas or sign of the dollar. For example, if your answer is $10,000, write it 10000)
