Forrester and Cohen is a small accounting firm, managed by Joseph Cohen since the retirement in December of his partner Brad Forrester. Cohen and his 3 CPAS together bill 640 hours per month. When Cohen or another accountant bills more than 160 hours per month, he or she gets an additional "overtime" pay of $63.80
for each of the extra hours: this is above and beyond the $5,100 salary each draws during the month. (Cohen draws the same base pay as his employees.) Cohen strongly discourages any CPA from working (billing) more than 245 hours in any given month. The demand for billable hours for the firm over the next 6 months is
estimated below:

- AG Sdn Bhd is an upcoming unit trust company led by Mr. Boo. This type of business relies heavily on the number of clients they obtain. This strategy will ensure their long-term business sustainability. Boo urges his staff to seek and gather clients and at the same time to aggressively promote their unit trust funds. Being a single man, he works tirelessly day and night and expects his staff to do the same. His employees consist mainly of school leavers who are mostly from the Baby Boomers or Generation Y categories. Hence, marketing methods are all set by Boo himself and all the agents are to follow the step-by- step process. Q1.

Epsilon Airlines services predominately the eastern and southeastern United States. A vast majority of Epsilon's customers make reservations through Epsilon's website, but a small percentage of customers make reservations via phone. Epsilon employs call-center personnel to handle these reservations along with any problems with the website reservation system and for the rebooking of flights for customers if their plans change or their travel is disrupted. Staffing the call center appropriately is a challenge for Epsilon's management team. Having too many employees on hand is a waste of money, but having too few results in very poor customer service and the potential loss of customers. Epsilon analysts have estimated the minimum number of call-center employees needed by day of week for the upcoming vacation season (June, July, and the first two weeks of August). These estimates are given in the following table. Day s.t. Monday Tuesday…arrow_forward

A soldier sells for $27 and uses $10 worth of raw materials. Each soldier that is manu- factured increases Giapetto's variable labor and overhead costs by $14. A train sells for $21 and uses $9 worth of raw materials. Each train built increases Giapetto's variable la- bor and overhead costs by $10. The manufacture of wooden soldiers and trains requires two types of skilled labor: carpentry and finishing. A soldier requires 2 hours of finishing labor and 1 hour of carpentry labor. A train requires 1 hour of finishing and 1 hour of car- pentry labor. Each week, Giapetto can obtain all the needed raw material but only 100 fin- ishing hours and 80 carpentry hours.

- I'm trying to find the capacity of a current line (on a conveyor-paced assembly). Each worker must perform at least one task. There are 6 tasks. Time to complete each task, starting with task 1, is 30, 25, 35, 40, 15, and 30 - all in seconds. There are 4 workers. Worker 1 completes Task 1; Worker 2 completes Task 2; Worker 3 completes Tasks 3 and 4; and Worker 4 completes Task 5 and 6.arrow_forwardA software support company has the following minimum personnel requirements “on duty” during the week. Each employee is required to have two consecutive days off. What are the minimum total regular employees required to satisfy the requirements?

An internal team aided by a hired consulting is also used. The payroll for the internal team is $500,000 for the first year and increases by $500,000 in years two and three. Also, $500,000 will be spent on consulting during the first year and $1,000,000 during each of years two and three. $2,000,000 will need to be invested in hardware during the second year and an additional $500,000 investment in hardware will be needed for year three. $200,000 in training will be needed the first year, $500,000 the second year, and $2,000,000 the third year. Management considers the expenditures for the first three years as investment in the system. Management estimates the operating cost of the system to be $2,500,000 (for personnel and other costs) in year 4 and to grow by 6% per year for years 5 through 10. The benefits are estimated to be $4,000,000 for year 4 and to grow by 30% per year for years 5…arrow_forward
