Re: [計量] The table above gives the inventory ...
※ 引述《sakuratea (櫻花茶)》之銘言：
: 1.
: Storehouse / Inventory of Grain / Shipping cost per ton
: #1 / 600 tons / $3
: #2 / 200 tons / $2
: #3 / 500 tons / $1
: The table above gives the inventory of grain for each of three
: storehouses and the cost of shipping grain to a particular customer.
: If the owner of the storehouse wishes to retain at least 50 percent
: of the inventory of each storehouse, what is the least possible shipping
: cost for an order of 600 tons?
: A) $600
: B) $700
: C) $1000
: D) $1200
: E) $1300
: Ans: D
要最省，又要每Storehouse都至少留50%
所以盡量從運費便宜的運
#3 250*1
#2 100*2
#1 (600-250-100)*3
合起來1200
: 2.
: If an organization were to sell n tickets for a theater production,
: the total revenue from ticket sales would be 20 percent greater than the
: total costs of the production. If the organization actually sold all but
: 5 percent of the n tickets, the total revenue from ticket sales was what
: percent greater than the production?
: A) 4%
: B) 10%
: C) 14%
: D) 15%
: E) 18%
: Ans: C
假設每張票x元
nx / (100%+20%) =Total costs
95%*nx = 114% * Total costs
所以選(C)
: 關於這2題有點霧煞煞...
