Question 3 A colliery has the capacity to produce 120 000 run-of-mine tons of anthracite (coal with high carbon content) per month. After washing, about two-thirds of the run-of-mine tonnage is sold as prime. The colliery is currently producing 96 000 run-of-mine tons per month. The fixed cost of the mine per month are R4,2-m and the variable cost per run-of-mine ton amounts to R45. Assume a selling price of R150 per ton of prime. Calculate the current profit made per month.
