Hi can someone help me with this question for accounting? Thanks

Sweet Acacia Manufacturing incurs unit costs of $7.50 ($5.50 variable and $2.00 fixed) in making a sub-assembly part for its finished product. A supplier offers to make 20,000 of the parts for $6.10 per unit. If it accepts the offer, Sweet Acacia will save all variable costs and $1.00 of fixed costs. Prepare an analysis showing the total cost savings, if any, that Sweet Acacia will realize by buying the part. (Round per unit answers to 2 decimal places, e.g. 15.25. If an amount reduces the net income then enter with a negative sign preceding the number, e.g. -15,000 or parenthesis, e.g. (15,000).)
