6*8.16=48.96
10*6.76=67.6
48.96+67.6=116.56
116.56/16=7.285
average of 7.29% nickel(nearest hundredth)

I see two other people already got it, but I can't believe how long it took people to catch on that there were different numbers of samples! That's kind of depressing.

8.16 (6) + 6.76 (10) = 48.96 + 67.6 = 116.56
116.56 / 16
7.29 %
