B, 50. because the triangle next to it is the exact same thing.
You're answer is going to be C
325.81
Hope this helps
I'm assuming this is a math question and all the tents equal the same thing, so to find the price for one tent, we would divide 40/3
Each tent is about $13.33
540ml with 12% solution
get 12% of 540
540 times 0.12 = 64.8 ml of pure acid
2 / -18 and 4/ a (1/2 ) I THINKKK
