easy right?

answer:

c = 4 a

step-by-step explanation:

the given function p(c) = - 15 c (c-8) is actually quadratic function:

p(c) = - 15c² + 120c     or parabola

the standard form of a quadratic function is:

y = ax² + bx + c

for which x is the maximum of the parabola we can find with this formula

x = - b/2a

in this case a = -15 and b = 120 and input variable is current c

c = - 120/(2 · (-15)) = - 120/ (-30) = 4 a

c = 4 a
