## anonymous 4 years ago How do I calculate this, I'm trying to explain my daughter's 4th grade homework to her. ..Adrian Dakota & Calvin made an average of 52 snacks Adrian & Dakota made an avereage of 61 snacks Dakota and Calvin made an average of 44 snacks. How many sancks did each individual make?

we can write down 3 equations if that helps $\frac{A+C+D}{3}=52$ $\frac{A+D}{2}=61$ $\frac{D+C}{2}=44$ and see if we can find what each of them are

or maybe we can just think. since $\frac{A+D}{2}=61$ that means $A+D=121$ so $\frac{A+C+D}{3}=\frac{C+121}{3}=52$ and so $C+121 = 3\times 52=156$therefore $C=156-121=35$

now the others should be easy

Thanks! I can't believe this is 4th grade math!!!

yeah i was trying to think of a way to do this in our heads, but i cannot. there might be a simpler way without equations, but i can't think of it
