Answer:
90.4 Grams
Explanation:
Hello Riley, I am going to answer the questions from our maths homework on here too from now on because I think it's fairly meaningless to let everyone else stay clueless.
30*90=2700
23*91=2093
(2700+2093) / (30+23) = 4793/53 = 90.4 grams
Ask any more, and I'll get back to them before it's due in.
