I would say 3:1, but i'm not positive! if i need to explain my reasoning, i can.
Answer:
(32, 16)
Step-by-step explanation:
Since the scale factor is 4, you always multiply both coordinate places (x and y) by this number.
The equation to calculate how many ways that "r" things can be chosen from a larger set of "n" things is:n! / [r! * (n-r)!] =
12! / (5! * 7!) =
12 * 11 * 10 * 9 * 8 * 7! / (5! * 7!) =12 * 11 * 10 * 9 * 8 / 5 * 4 * 3 * 2 =11 * 9 * 8 =792 ways

Find the intersection point between the 2 restraint equations:
30 - 2x = 12 - \frac{1}{2} x \\ \frac{3}{2} x = 18 \\ x = 12
Substitute back in to find y-value:
y = 30 - 2(12) = 6
P is maximized at point (12,6)
P = 9(12)+9(6) = 162
