[計量] this year a city allotted ...
this year a city allotted(撥出的) 60 percent of its budget
for school expenditures, and its budget is 15 percent higher
than last year's budget of n dollars. In terms of n, how many
dollars of this year's budget has the city allotted for
school expenditures?
A) (0.6)(0.85n)
B) (0.6)(1.15n)
C) 0.6n/1.15
D) 0.85n/0.6
E) n/1.15+0.6n
答案是B
我有點看不懂意思，不知道n是last year school expenditures 的
還是last year 整個的budget
希望有大大可以幫我解惑，謝謝。
