The following is a partially completed lower section of a departmental expense allocation spreadsheet for Haston Bookstore. It reports the total amounts of direct and indirect expenses allocated to its five departments. Complete the spreadsheet by allocating the expenses of the two service departments $($advertising and purchasing$)$ to the three operating departments. This problem is almost the same as the class problem. See the class problem solution video if you feel stuck.

Advertising and purchasing department expenses are allocated to operating departments on the basis of dollar sales and purchase orders, respectively. Information about the allocation bases for three operating departments follows.
