You are looking for the ways for partitioning a set with 66 elements in three subsets. If you allow empty subsets, the answer is given by

Credits to https://math.stackexchange.com/questions/2176796/how-many-ways-are-there-to-put-6-balls-in-3-boxes-if-the-balls-are-distinguishab for solution

Doesn't seem to work. I entered in 3.6pi, then 18pi/5.

I can't enter anymore, but I am still curious for the solution.

First, we need acknowledge that 25 is the fixed number.

67 - 25 = 42

210/42 = 5

This means that 5$ is charged every mile.

Thus, we obtain

C = 25 + 5x

Let the amount of sales of item A be 'a', and the amount of sales of item B be 'b'.

then since a sales for 50$, you get 50a. since b sells for 25$, you get 25b.

Therefore, since the total revenue is $1500, you have for the final equation:

50a + 25b = 1500

Thank you!!!!

x^2 + 2(3x) + 3^2

simplified is

----->>  x^2 + 6x + 9 <<-------

But i will still try to answer some problemos 

If is says P([something],[something]) then it has to do with permutation. I dont know what that would really do, black. So go search up permutations calculator on like the web or something
