A sum of positive natural numbers adding up to n is called a partition of n. For
instance, 1+2+4 is a partition of 7. As none of the summands 1, 2, 4 are equal, this
is called a partition into unequal parts. Does this help? Because this is all I know :(
Divide the total by the quantity of numbers:
852/3 = 284
Because there are an odd quantity of numbers (3) the answer is the middle number.
The answer is 284
There was a
66
% increase from Sari's sales from November to December.
To find the percentage increase in her sales, we must first find the amount her sales increased. We can do that by subtracting the greeting cards sold in November from the number of greeting cards sold in December. Substituting values and simplifying, we get that she sold 200 more greeting cards in December.
To find what percent increase this is, we must find what percent 200 is of the number of greeting cards sold in November. We can do this by dividing 200 by the number of cards sold in November (300), and then multiplying by 100 (to make it a percent). Doing this, we get

* 100 which gives us our answer of
66
%.
