Lifetime has collected demand forecasts for its kayaks in Table 2. They would like to compare the total cost of two plans: 1) A chase strategy using hires/layoffs with no inventory and backorders; and 2) A Level strategy using inventory and backorders. To help with the comparison, they have obtained other relevant costs and production information in Table 1. They will start the planning horizon with 0 units in initial inventory. Assume all backorders accumulate.

Table 1

Production cost per unit	$190
Hiring cost per unit	$50
Layoff cost per unit	$90
Cost of holding inventory per unit per month	$50
