Answer:
20%
Step-by-step explanation:
First, I added them up. From the things we know, blue, red, green, yellow combined equals 16 marbles. 20-16 equals 4. So there are 4 white marbles. 4/20 times 5 equals 20/100. So the percent of the marbles that are white is 20%.
Z=kx, 30=8k, so k=30/8=15/4 and z=15x/4, so when x=4, z=15.
Y= 17 would be the answer.
For something to be a function, it needs an input (x) and an output (y).
There is no x is this answer.
I hope this helps!

Profit will be achieved when the money earned is greater than the money spent so,
336 + (n*12) = n*28 any subsequent units sold would result in profit
336 = 28n - 12n
336 = 16n
=> n = 336/16 = 21
21 units must be sold to draw even any more would result in profit
