A manufacturer has developed the following regression model from the past 60 months of operating datat Monthly packing cost=580 +2.25 A+1.10 B+5.200 Where: A-number of orders B - weight of orders in pounds: C=number of fragile items An appropriate interpretation of this model is that: O A. Number of orders is expected to be at least 580. O B. The average weight per order is 1.10 pounds. OC. Weight of orders is the least important cost driver for estimating packing cost. D. Each fragile item shipped will increase packing cost by, on average. $5.20
