2.问题:
(1)开工预付款金额为多少
(2)开工预付款的起扣月是第几月
(3)计算从起扣月开始每个月应扣回的金额。

答案

参考答案:(1)开工预付款金额=2000×10%=200万元
(2)开工预付款的起扣月是第4个月
因为第3个月的累计支付=100+150+250=500万<30%×2000万元
第4个月的累计支付=100+150+250+300=800万>600万,800/2000=40%
(3)计算从起扣月开始每个月应扣回的金额。
第4个月的开工预付款扣回=[(800-600)/2000]×2×200=40万元,累计40%
第5个月的开工预付款扣回=(400/2000)×2×200=80万元,累计60%
第6个月的开工预付款扣回=(300/2000)×2×200=60万元,累计75%
到第7个月的累计支付=1800万元,累计90%>80%
第7个月的开工预付款扣回=200-40-80-60=20万元
计算过程也可参考以下计算表:

月份 1 2 3 4 5 6 7 8 9
实际支付 100万元 150万元 250万元 300万元 400万元 300万元 300万元 20万元 20万元
实际累计支付 100万元 250万元 500万元 800万元 1200万元 1500万元 1800万元 1820万元 1840万元
实际累计百分数 5% 12.5% 25% 40% 60% 75% 90% 91% 92%
开工预付款扣回 0 0 0 40万元 80万元 60万元 20万元 0 0
预付款累计扣回 0 0 0 40万元 120万元 180万元 200万元

     In the United States you will find yourself being urged from every page of  every newspaper and every

television station to buy all kinds of goods.

     Not only is there a wide range of prices for goods in America, there is also a wide range in the quality

of goods offered for sale. Unlike some countries,

     Americans generally pay the price of a product without question, instead of trying to get a lower price

by bargaining. However, there are many "sales" in the United States, during which time stores will lower

their normal prices. This may all be very confusing to visitors. How are you going to know how to "get

your money's worth" when you shop? Perhaps the best advice is: Don't hurry. Visit various stores and

determine the quality of goods. Read the advertisements so that you can compare prices.

     There is a great variety of shops in the United States, ranging from very large stores called "department stores" to very small shops. There are "discount houses" offering goods at low prices, and "dime stores"

specializing in a wide range of inexpensive items.

     Most department stores in large cities carry better quality products at higher prices. However, they

offer the shoppers great convenience since they contain such a wide variety of products.

     If convenience isn't as important to you as price, you may want to shop in discount houses. These

stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do

so for several reasons. They don't offer the same services to buyers that department stores do; there may

be fewer sales people; and the store probably doesn't deliver purchases.

     Another popular shop is the "dime store". No longer selling many things for five or ten cents, these

stores got their name in the last century when it was decided that a small profit on a great quantity of

goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of

inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.
