Development planners determined the number of new housing units needed in a certain area by using the formula H = kJ, where H is the number of new housing units needed in the area, J is the number of new jobs to be created in the area, and k is a constant.How many new housing units did the planners determine were needed?

(1)The number of new jobs to be created was 60,000.

(2)According to theformula used by the planners, if 37,500 jobs were to be created, then 7,500 new housing units would be needed.

這條答案是 C.
請問 (2) 那個 7,500 是不是指假設所得的housing units, 而不是題目所要找的 new housing units. 所以我們只能用(2) 找出 k, 而不是H?

lz理解的没有错条件2是给你一个假设（IF。。。。。）所以当然不是题目要你求的数量
