I rebuilt the shower into a bathtub and tiled the walls and ceiling with 3x6 subway tiles using Custom's FlexBond mortar and Fusion Pro grout. According to Custom, both of these products are adequate for bathroom use except for a shower floor.
The 2016 cost of production estimates for corn, soybeans, and wheat show costs nearly the same as those forecast for 2015. To be specific the budgeted costs range from $8.48 (corn) to $5.00 per acre (wheat) higher than 2015.
For purposes of comparing how average total cost can change based on production, let's set output (Q) at 4,000 in July and 6,000 in August. In July, our total cost is $50,000 + $100(4,000) = $450,000. Once we have total cost, we can divide that by our quantity produced to get average total cost. For July, $450,000 / 4,000 = $112.50. In July, each monitor produced cost $112.50. Using the same formula for August but increasing production, results in an average total cost of $108.33.
