CPT N = years ? Suppose you want to buy a new house. You currently have $15,000 and you figure you need to have a 10% down payment(頭期款) plus an additional 5% of the loan amount for closing costs(買賣手續(xù)費) . Assume the type of house you want will cost about $150,000 and you can earn % per year, how long will it be before you have enough money for the down payment and closing costs? ? How much do you need to have in the future? ? Down payment = .1(150,000) = 15,000 ? Closing costs = .05(150,000 – 15,000) = 6,750 ? Total needed = 15,000 + 6,750 = 21,750 ? Compute the number of periods ? PV = 15,000。紐約布魯克林法院判決田納西鎮(zhèn)應(yīng)向美國投資者支付這筆錢。 斯蘭黑不動產(chǎn)公司在內(nèi)部交換銀行 ( 田納西鎮(zhèn)的一個銀行 ) 存入一筆6億美元的存款 。可用絕對數(shù)(風(fēng)險報酬額)和相對數(shù)(風(fēng)險報酬率)表示。假設(shè)未來的經(jīng)濟狀況只有三種:繁榮、正常和衰退,要求求出兩個項目的風(fēng)險報酬率。不可分散風(fēng)險的程度通常由 223。 ( 1)現(xiàn)在一次性存入一筆款項,問需存入多少錢?
