The Bonawitz Corporation has a central copying facility. The copying facility has only two users, the Marketing Department and the Operations Department. The following data apply to the coming budget year: Budgeted costs of operating the copying facility for 200,000 to 300,000 copies: Fixed costs per year $30,000 Variable costs 3 cents (.03) per copy Budgeted long-run usage in copies per year: Marketing Department 60,000 copies Operations Department 190,000 copies Budgeted amounts are used to calculate the allocation rates. Actual usage for the year by the Marketing Department was 40,000 copies and by the Operations Department was 180,000 copies. If a single-rate cost allocation method is used, what amount of copying facility costs will be allocated to the Marketing Department? Assume actual usage is used to allocate copying costs.

the answer is 6000 but I don't know how to get that number. could you please show me the calculation.thank you
