Workers are compensated by firms with “benefits” in addition to wages and salaries. The most prominent benefit offered by many firms is health insurance. Suppose that in 2000, workers at one steel plant were paid $35 per hour and in addition received health benefits at the rate of $7 per hour. Also suppose that by 2010 workers at that plant were paid $36.75 per hour but received $31.5 in health insurance benefits.

a. By what percentage did total compensation (wages plus benefits) change at this plant from 2000 to 2010?

total compensation increased or decreased(choose one) by _______ percent

What was the approximate average annual percentage change in total compensation?

b. By what percentage did wages change at this plant from 2000 to 2010?

wages increased or decresed (choose one) by ________ percent

What was the approximate average annual percentage change in wages?

c. If workers value a dollar of health benefits as much as they value a dollar of wages, by what total percentage will they feel that their incomes have risen over this time period?

What if they only consider wages when calculating their incomes?

incomes increased or decreased (choose one) by _____ percent

d. Is it possible for workers to feel as though their wages are stagnating even if total compensation is rising?

Suppose that Weston (WN) currently is selling at $80 per share. You buy 250 shares, using $15,000 of your own money and borrowing the remainder of the pur- chase price from your broker. The rate on the margin loan is 8%.

a. What is the percentage increase in the net worth of your brokerage account if the price of WN immedi- ately changes to (i) $88; (ii) $80; (iii) $72? What is the relationship between your percentage return and the percentage change in the price of WN?

b. If the minimum margin is 30%, how low can WN's price fall before you get a margin call?

c. How would your answer to (b) change if you had fi- nanced the initial purchase with only $10,000 of your own money?

d. What is the rate of return on your margined position (assuming again that you invest $15,000 of your own money) if WN is selling after one year at (i) $88; (ii) $80; (iii) $72? What is the relationship be- tween your percentage return and the percentage change in the price of WN? Assume that WN pays no dividends.

e. Continue to assume that a year has passed. How low can WN price fall before you get a margin call?

Adventures & Vacations LLC bought a parcel of land and plans to build luxury villas on the property. The owners of the company plans to build four types of villas: deluxe non-smoking villas, deluxe villas that allow smoking, premier non-smoking villas and premier villas that allow smoking. Your team works for a consultant company that was hired to help the company plan the how many rooms of each type to build. You were given these following information by Adventures & Vacations LLC: Considering the industry trends, villas that allow smoking should be more more than 50% of the number of non-smoking rooms. There should be at least 100 but no more than 180 deluxe rooms Estimated construction costs the types of rooms are as follows: Deluxe villa = $12,000 and Premier villa = $15,000. Any villa that allow smoking will have additional systems and equipment added such as multiple smoke detectors, fire extinguishers, sprinklers and air purifiers. The estimated cost of this additional system is $3000. Adventures and Vacations LLC already raised $6.3 million in construction guarantees for this portion of the building. The expected per night revenues for the villas are: $130 for Deluxe villas and $175 for Premier villas. These prices are for non-smoking rooms. Guests will be charged an extra $15 per room if they choose to stay at villas that allow smoking. After consulting with the architect, the most aesthetically viable design for the property require that the number of deluxe rooms be at least 1.5 times the number of the premier rooms, but no more than 2.5 times. Instructions: 1) Your team's job is to design the LP model to help Adventures and Vacations LLC determine the best mix of rooms to construct. Note: Show your complete LP model for this problem. There is no need to solve. Make sure to include the following: Objective Function Constraints 2) Briefly discuss your rationale or reasoning for the LP model you are recommending. 3) What were some of the challenges you experienced when you were formulating the model?

Jones Souvenirs Hut does customized, hand-crafted memorabilia for hotels, in which each batch of souvenirs is a job. The company uses a perpetual inventory system and has a highly labour-intensive production process, so it assigns manufacturing overhead based on direct labour cost. Joust’s predetermined overhead rate for 2017 was computed from the following data:

Total estimated factory overhead $2,400,000

Total estimated direct labour cost $2,000,000

The WIP account given below relates to the activities of Jones Souvenirs for the month of April:

WIP Inventory A/C

? Other manufacturing overheads incurred ………………… $94,275

? Two jobs were completed with total costs of $183,000 and $105,000 respectively. They were sold to the hotel on account at a margin of 33 1/3% on sales.
