I mean if you chose Alpha, you're swinging from A to B-; and from Beta, swinging from B+ to C.

要是你选α,你的分数会在A到B-,选β,分数范围会在B+到C

Let's multiply both sides by 2, I'll get 2q1* is equal to a - c over b - q1*.

等式两边同时乘以2,得到,2q1*=/b-q1

I claim this quantity is a - c over b such that if Firm 2 produces that much quantity, firm 1 will just produce nothing.

这个量是,/b,如果公司2生产这么多公司1就会停产

I have 3 q1* is equal to a - c over b; and finally divide by 3 q1* is equal to a - c over 3b.

q1*= /b,最后两边同除以3得,q1*=/3b

She costs C for sure, that's a wash because B, the way we've worked things out, B was $2, C was $1, So B/2-C is a wash.

她承担C的成本,收益是零,因为B,按我们设定的金额,B是2美元,C是1美元,所以B/2-C是零

So this is a - c over b and this is a - c over 2b so this distance and this distance are meant to be the same.

这点是,/b,这点是,/2b,这两段长度应该是相等的

What q2 makes this equal to 0 and Katie's answer is solving out the algebra here is that q2 that solves this must be a - c over b.

2为何值时这个算式等于0呢,凯特回答其实就是算出这个的解,即,q2=/b
