Automobiles of the future will most likely be manufactured largely with carbon fibers made from recycled plastics, wood pulp, and cellulose. Replacing half the ferrous metals in current automobiles could reduce a vehicle’s weight by 60% and fuel consumption by 30%. One impediment to using carbon fibers in cars is cost. If the justification for the extra sticker

- A bookstore purchased a best selling book at P200 per copy. At what price should this book be sold so that, giving a 20% discount, the profit is 30%.arrow_forwardA salesman from vendor A, who is trying to get his foot in the door at Filerbee, Inc., offered water desalting equipment for $2.1 million. This is $400,000 more than the price that a saleswoman from vendor B offered, if purchased and paid for now. However, as a special offer, vendor A said Filerbee won’t have to pay until the warranty runs out. If the equipmenthas a 2-year warranty, determine which offer is better. The company’s real MARR is 12% per year and the inflation rate is 4% per year.arrow_forwardIt costs 100, 000 pesos at the end of each year to maintain a certain portion of a highway. If money is worth 10%, how much would it pay to spend immediately to reduce the annual cost to 40,000 pesos?arrow_forward
- The council members of a small town have decided that the earth levee that protects the town from flooding should be rebuilt and strengthened. The town engineer estimates that the cost of the work at the end of the first year will be $68,000. He estimates that in subsequent years the annual repair costs will decline by $7000, making the second-year cost $61,000; the third-year $54,000, and so forth. The council members want to know what the equivalent present cost is for the first 5 years of repair work if interest is 6%.arrow_forwardA process has a cycle time of 10 minutes. The throughput time is 10 hours. If the throughput time is reduced to 5 hours without changing the cycle time, what is the change in inventory (as a percentage)?arrow_forwardThe Daily Charge is determined by using the Room Number and Rate Code to lookup the value in the DailyChg worksheet. Use the XLOOKUP() function with a nested XLOOKUP() function to find the correct daily charge and display it in column I of the Reservation worksheet. • Use the IFS function to determine the seating surcharge (column K) based upon the value in column H. The seating codes are: CI, CL, LE, US. The CI seating style costs an addition $50, CL is the standard - for which there is no additional charges, LE is an upcharge of $125, and US costs an additional $200. Don't hardcode the values in the function, but rather, create an input area on the DailyChg worksheet. Calculate the Reservation's Total Charges using formula of Daily Charge * Booked days + Seating Surcharge.

- A new automotive “dry paint” separation process is environmentally friendly and is expected to save $8.00 per car painted at a Detroit plant. The installed cost of the process is $8 million, and 250,000 cars are painted each year.What is the simple payback for the new technology?arrow_forwardA local financing bank granted a car loan to a man who agreed to pay a rate of interest of 20%. Interest in this type of transaction is to be deducted from the loan at the time the money is released. At the end of one year, the borrower will have to pay the same amount that is stated in his loan application. What actual interest did the financing bank charge him? Do a manual solution.arrow_forwardDuring periods of hyperinflation, prices increase rapidly over short periods of time. One of the worst cases of hyperinflation in history occurred in Zimbabwe in 2008 where prices doubled every day. If that rate continued for just 7 days, how much would a French baguette cost after 7 days if the cost at the beginning of the week was $0.6? The cost after 7 days will be $ .arrow_forward
- Shin likes to spend a (relatively small) portion of his income on vacations to Cabo San Lucas (a popular resort area in Mexico). On these trips, he either stays at a four-star resort with panoramic ocean views or a more modest, and slightly deteriorating hotel in the noisy part of town. Understandably, the four-star hotel is significantly more expensive. Suppose that the four-star hotel costs $5000/trip while the hotel costs just $500/trip. In recent years, the price of airfare has risen significantly, a change that affects the cost of his trips the same regardless of where he stays. Suppose that airfare has increased from $300/trip to $1000/trip. Why is it that following the higher travel prices, Shin is likely to spend more of his vacations at the four-star resort when he travels? (Assume that the hotel rates and Shin's preferences are fixed).arrow_forwardDuring periods of hyperinflation, prices increase rapidly over short periods of time. One of the worst cases of hyperinflation in history occurred in Zimbabwe in 2008 where prices doubled every day. If that rate continued for just 1 week, how much would a French baguette cost after 7 days if the cost at the beginning of the week was $1.25?arrow_forwardThe maximum amount an individual can contribute to her Registered Retirement Savings Plan (RRSP) for a year is set by the Canada Revenue Agency. For the year 2011, the maximum contribution was the lesser of $21450 or 18% of the individual's "earned income" in 2010. The lowest amount of earned income for 2010 at which an individual could make a $21450 contribution in 2011 is $ Do not round your answer!
