Determine the following, presenting your computations (Prepare your computations using unit cost data to four decimal places, i.e. $4.4444, to minimize rounding differences): Assuming that the direct material cost per unit is the same for October and November, by how much the conversion cost per unit increase and/or decrease from October to November?
