What we discussed were 5 euroes per 10 meters that equals to 4 euroes per 7 meters.

At that time, we talk about the 10 meters five euros, the equivalent of seven meters € 4

这里的谈不是谈论的意思而是指谈好了说定了，所以应该是：just then we agreed to 5 euroes for 10 meters, so it is 4 euroes for 7 meters.

We agreed at that time that the price of ten meters is five Euros, which means the price of seven metres is four euros.
