Compute the updated echelon base-stock levels for the Stage Three Incorporated example given the same distribution of demand at the field warehouse, but with a penalty cost that is 20% of the original value (i.e., b = $10) and a 50% increase in echelon holding costs (i.e., installation holding costs of h3 = $3.00, h2 = $2.25, and h1 = $1.50).
