Gregory and Hayes suggest four policy changes to reduce the value of the average inventory (page 7 in the case). For each suggested change below, estimate the savings that can be expected if the change is successfully implemented and discuss if the estimated savings can compensate for the increase in inventory of $1.6 million. a. It is estimated that for 10% of all products, Scientific Glass maintains too high of a service level. Assuming this high service level is 99.9% suppose the company enforces a strict 99% service level.

i. Using data from the case and Exhibit 3, complete the table below.

Product Griffin Beaker Erlenmeyer Flask

Required:
a. Calculate the percentage saved in the average Inventory by lowering the service level from 99.9% to 99% for each product.
b. Estimate the total inventory savings by taking a simple average of savings for the two representative products and applying this average to the 10% of products. Assume that 10% of products account for 10% of the 2010 inventory value of $10 million.
c. Comment if the calculated savings compensate for the estimated $1.5 million increase in inventory.

of the three mortgage options that demarco and tanya have to choose from, the balloon payment mortgage would be their best option, over adjustable payment and fixed payment plans.ultimately, the balloon payment plan would save demarco and tanya overall, in interest, would cost less monthly, and they would only have to make these payments for 8 years, opposing to 30 years for adjustable or fixed payment plans. 

overall, demarco and tanya would save $80,811 if they chose balloon payments over fixed payments, and would save $116,711 if they choose balloon payments over adjustable payments. benefits with choosing fixed payments over adjustable payments is that, in the end, the payments will still be $836.30 a month, while with adjustable payments, the initial monthly payments will be $763.38 to $1082.70 a month, ultimately leading to a more costly purchase. benefits with choosing fixed payments over balloon payments are not present. benefits in choosing adjustable payments over is that it has a lower interest rate, and starts with lower monthly payments initially. benefits in choosing adjustable payments over balloon payments include a lower interest rate, and lower initial monthly payments. benefits in choosing balloon payments over fixed payments include lower interest rates, lower overall price, lower monthly payments, takes less time to pay off, and does not require a downpayment. benefits in choosing balloon payments over adjustable payments include, lower monthly payments (when averaged), takes less time to pay off, and lower overall price.

hence, option c, balloon payments, is the best option for demarco and tanya to make this purchase, for it will save them a minimum of $80811, and a maximum of $116,711. 

all you have to do is give a good answer with details and the answer has to be understandable and then they will most likely give you the brainliest answer.
