The average number of chocolates in the first 10 boxes is 3,200, and in the next 12 boxes is 4,500. How many total number of chocolates are there in these 22 boxes?

Using the sum and average relationship, the total chocolates in the first 10 boxes is 10 multiplied by 3200, which equals 32000. The total chocolates in the next 12 boxes is 12 multiplied by 4500, which equals 54000. Adding these two amounts gives a total of 86000 chocolates in the 22 boxes.
