nonlinear budgef8 Ralph's manufaeturing cost (TMC) is estimated as follows, where q denotes units manufaetured:

TMC = 8,000 + 6q, if 0 ::s; q ::s; 2,000;

TMC = 10,000 + 5q if 2,000 ::s; q::s; 4,000; and TMC = -2,000 + 8q if 4,000 ::s; q.

Plot Ralph's manufaeturing cost. Detennine the ineremental cost of 50additional units if (i) Ralph is eurrently manufaeturing 1,800 units, or (ii) Ralph is eurrently manufaeturing 1,990 units.
