Answer:
8$
Step-by-step explanation:
Maximum value is found by solving the root of the first derivative. that root is where the maximum value is.
f ' (x) = -8(x - 6) = 0.
So x = 6 and that's the maximum value. f(6) = 3
2cos(2x - π) + 4 is a trig function. The maximum value of cosine function is 1.
So the maximum value would be 2(1) + 4 = 6.
divide the discount by the percentage off
so:
99.90/0.27 = 370
the original price was 370 dollars
