Cost to the college for performing its house keeping services
Cleaning Supplies costs = $ 3 per hour x 3120 hours = - $9360
Direct Labour Costs = $ 27 per hour x 3120 hours = - $84240
Variable Overheads costs = $ 2 x 3120 hours = - $6240
Total Fixed Costs = - $51840
Total Cost to the college = 9360 + 84240 + 6240 + 51840 = $151680
Cost to the College for Outsourcing
We will assume house keeping hours are still 3120
house keeping service cost per hour = $ 50 x 3120 = - $156000
Total Fixed costs = $51840 x 50/100 = - $25920
Total Costs to the College for outsourcing = 156000 + 25920
Total Costs to the College for outsourcing = $181920
