Question

Answer

If Charles used u kg of flour, Danny used u + 1/4 kg and  Emily used 2(u + 1/4) kg.

Given the total mass used 8 3/4 kg,

u + u + 1/4 + 2(u + 1/4) = 8 3/4

4u + 3/4= 35/4

4u = 8

u = 2

So Charles used 2 kg of flour.

I think the question is, how on earth did the teacher come up with 16 in his/her answer?  I also want to know… 🙂
