Windsor Manufacturing incurs unit costs of $8.30 ( $5.30 variable and $3.00 fixed) in making a sub-assembly part for its finished product. A supplier offers to make 12,000 of the parts for $5.90 per unit. If it accepts the offer, Windsor will save all variable costs and $1.00 of fixed costs. Prepare an analysis showing the total cost savings, if any, that Windsor will realize by buying the part. (Round per unit answers to 2 decimal places, e.g. 15.25.
