Charlene has been in the business of servicing computers and computer systems at affordable prices for just over five years. Her company's primary clients are local businesses but include some residential customers Their advertised approach is to analyze the problem, develop a range of IT options, explain their specific recommendation to the customer, and finally estimate the time and costs associated with the service prior to commencing work Their approach has proven successful, but competition is getting much stiffer, and Charlene is concerned that her approach to determining costs for any particular job is not correctly incorporating all of the company's indirect costs. She asks her accountant to create an allocation system for assigning indirect costs to jobs. Her accountant decided to implement a single-driver allocation system and needed to develop a reliable cost function to estimate total indirect costs (the numerator of the single driver allocation rate). The accountant plans to use service hours as the cost driver in the allocation process and as the activity measure in the cost function. She estimated the parameters of the indirect cost function by analyzing the behavior of last month's indirect costs, when the company spent 294 service hours repairing 25 computer systems. Here are the results of her analysis Cost Item Utilities Office rent Administration Supplies Training Total Fixed Cost Variable Cost $205 $139 3,754 0 3,142 232 0 3,111 320 $7,421 343 $3,825 After giving it some more thought, the accountant was somewhat concerned that last month may not have been a typical month, so she created a different set of cost function parameters using the high-low method. She collected total cost and activity data from the last six months; the following were for the two months when costs and activity were at the lowest and the highest levels Total indirect costs Service hours Computer systems serviced Next month, Charlene expects the company to spend 450 hours solving clients' computer system problems. low month 10,420 high month $11,113 236 558 30 70 REQUIRED (ROUND ALL PER-UNIT COSTS TO TWO DECIMAL PLACES.] Part A (5 tries; 5 points] If the accountant uses the cost function based on her analysis of last month's costs, what is her estimate of total indirect costs next month?
