Average weight of a package?

Step-by-step explanation:

average weight can be find as;

average=sum of quantity/no. of quantity

or sum=avg*no. of quantity.

now,

first shipment has total 7.4*10= 74 pound

second shipment has total 12*8.2=98.4

third shipment has total 6*8.7=52.2

now calculating the average of all three we get.

avg=(74+98.2+52.2)/3=74.7
