The variable cost, which includes material, labor, and shipping costs, is $32 per doll. During the holiday selling season, FTC will sell the dolls for $40 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll.

Sara is a 57-year-old graphic designer who wants to retire 5 years from now. She earns $54,000/year and does not expect any raises if she stays in her job. Her daughter has told her about a new job opportunity that would offer a much higher salary, but to become eligible Sara would need to quit her job and spend a year taking classes. If she did that, next year she would earn $0 and pay $42,000 in tuition, and then she would earn $81,000/year for the final 4 years of her career. Sara likes the duties of the two jobs equally well, so this is strictly a financial issue for her. The interest rate is r. Question: How will she decide? Write down the calculation she will make. Would she be more likely to change jobs if the interest rate were higher or lower?
Mr. Saleh is one of the school canteen operators who joined The Supplementary Food Plan (RMT) organized by the Ministry of Education Malaysia. Assuming that each RMT student has been allocated RM3-RM4 for his meal per day. Due to that, Mr. Saleh needs to prepare one meal set consisting of one chicken rice and a box of milk for each RMT student.
