2. Using the cost formula you derived above, what amount of custodial supplies expenses would you expect to be incurred at an occupancy level of 11,000 guest days?




expect to be incurred at an occupancy level of 11,000 guest-days?

Explanation / Answer

1. Using High low method, Variable Cost per day= (13500 - 7500) / (12000-4000) =$0.75 Fixed Cost = 7500 - (0.75*4000) =$4,500 Cost Function, C = 4500 + 0.75 D where, C = total Cost D = Guest Days 2. Expense = 4500 +0.75 *11000 = $12,750
