3. A cement kiln with production capacity of 130 tons/day (24 hours) of clinker has its burning zone about 45 tons of magnesite chrome bricks being replaced periodically depending on some operational factors and the life of the bricks. If locally produced bricks costsP25,000/ton, and have a life of 4 months, while certain imported bricks costing P30,000/ton and have a life of 6 months, determine the more economical bricks and by how much?

6. Machine A and Machine B are being considered for the production of a part of a product. The impor- tant differences between the machines are: Machine A Machine B 100 parts/hr 130 parts/hr Production rate Hours available for production Rejection rate 7 hrs/day 6 hrs/day 3 % 10 % The material cost is $6.00 per part, the operator cost is $15.00 per hour, and the variable overhead cost is $5.00 per hour. All defect-free parts produced can be sold for $12 each, and the rejected parts have no value. Assume that the daily demand for this part is large enough that all defect-free parts can be sold. Which machine should be selected? • What should the rejection rate be for Machine B to be as profitable as Machine A?
3 Your company plans to raise price on product A by 5% per year. Due to competition, sales volume from product A is expected to decline at 10% per year. Revenue will be $5M for this year. Alternatively, based on the projection from the marketing department, you may reduce the sales volume decline from 10% to 5% if the price is kept unchanged. The product will be discontinued at the end of year 5 for both scenarios. If the firm's TVOM is 10%, Determine the revenue cash flow streams for both alternatives. What is the Excel financial function to compute PW of the revenue streams
A university is trying to determine how much it should charge for tickets to basketball games to help offset the expenses of the new arena. The cost to build the arena including labor, materials. e tc. was $92 million. Each year the maintenance cost is expected to increase by 5% as the building gets older. 1l1e maintenance cost for the first year is $150.000. Utilities arc expected to average about $200.000 per year and labor costs $300,000. The average attendance at basketball games over the year is expected to be J00.000 people (or 100.000 tickets sold to events). Assuming the arena has no other source of income besides regular ticket sales (not including student tickets) for basketball games, what should the university charge so that it can recover at least a 6% cost of borrowing on its investment? ll1c university expects the arena to be used for 40 years and 10 have no appreciable salvage value.

. A manager has been presented with two proposals for automating a production process. Proposal A involves an initial cost of $15,000 and an annual operating costof $2,000 per year for the next 4 years. Thereafter, the operating cost is expected to increase by $100 per year. This equipment is expected to have a 10-year life with no salvage value.Proposal B requires an initial investment of $28,000 and an annual operating cost of $1,200 per year for the first 3 years. Thereafter, theoperating cost is expected to increase by $120 per year. This equipment is expected to last for 20 years and will have a $2,000 salvage value. If the company's minimum attractive rate of return is 10%, which proposal should be accepted on the basis of present worth analysis?

Please no written by hand and no emage An automobile dealer can sell 8 sedans per day at a price of $20,000 and 4 SUVs (sport utility vehicles) per day at a price of $25,000. She estimates that for each $400 decrease in price of the sedans she can sell two more per day, and for each $600 decrease in price for the SUVs she can sell one more. If each sedan costs her $16,800 and each SUV costs her $19,000, and fixed costs are $1,100 per day, what price should she charge for the sedans and the SUVs to maximize profit? [Hint: Let x be the number of $400 price decreases for sedans and y be the number of $600 price decreases for SUVs, and use the
