A company manufactures several products. The fixed costs assigned to Product 'A' are $8,000 per month. The variable costs are $4.00 per unit produced. The per unit price (p) at which this product can be sold is related to the quantity sold per month (D) with the equation p = $35 - 0.02D. Find the optimal monthly sales volume at which the profit is at the maximum level and find the value of this profit level. Also, find the range of values for the monthly sales volume for which there is no loss.
