Guadalupe Electric, Inc. must replace a robotic Mig weider and is evaluating two alternatives. Machine A has a fixed cost for the first year of $84,000 and a variable cost of $14, with a capacity of 21,000 units per year, Machine B is slower, with a speed of one-half of A5, but the fixed a is only $50,000. The variable cost will be higher, at $19 per unit. Each unit is expected to sell for $24. a) What is the crossover point (point of indifference) for the two machines? The crossover point for the two machines is units. (Round your response to the nearest whole number.)
