Plan B: Vary the workforce to produce the prior month's demand. Demand was 1,300 units in June. The cost of hiring additional workers is $30 per unit produced. The cost of layoffs is $65 per unit cut back. (Enter all responses as whole numbers.) Note: Both hiring and layoff costs are incurred in the month of the change (i.e., going from production of 1,300 in July to 1300 in August requires a layoff (and related costs) of 0 units in August)
