A paper pulp company has discovered their cost and revenue functions for each day: C(x) = 2x? - 250x + 525 and R(x) = -3x? + 750x + 125, where x is the amount of pulp in tons. If they want to make a profit, what is the range of pulp in tons per day that they should produce? Round to the nearest tenth of a ton which would generate profit. 199.0 tons 199.5 tons 199.6 tons 200.0 tons
