Machine A has a fixed cost for the first year of $$$$83,000$ and a variable cost of $$$$12$ with a capacity of $12,000$ units per year. Machine B is$$ slower, with a speed of$$ one$-$half of$$ A$\text{'}$s$,$ but the fixed cost is only $$$$62,000.$ The variable cost will be$$ higher, at $$$$16$ per unit. Each unit is expected to sell for $$$$21$
