两道GMAT OG 我感觉答案错了,
1.A certain manufacturer produces items for which the production costs consists of annual fixed costs totaling $130,000 and variable costs averaging $8 per item.If the manufacturer's selling price per item is $15,how many items must the manufacturer produce and sell to earn annual profit of &150,000?
a.2858 b.18667 c.21429 d.35000 e.40000
2.if positive integers x and y are not both odd,which of the following must be even?
a.xy b.x+y c.x-y d.x+y-1 e.2(x+y)-1
1.答案:c 思路:150000除以(15-8)=21428.5.
2.这题楼主自己想.“positive integers x and y are not both odd” 意思就是x和y不同时是奇数.但本人估计就是x,y是一奇一偶,或都是偶.
第一题题目楼主打错的字太多了~
