Answer:
Step-by-step explanation:
B
Answer: The symbol is < for both
$11,714
C(x) = 0.7x² - 462x + 87,944
this is a quadratic equation that opens up
the vertex will be the minimum
From the quadratic formula the x coordinate of the vertex is
x = -b/2a
x = 462/(2 * 0.7)
x = 330
Plug in
c(330) = 0.7(330²) - 462(330) + 87,944
c(330) = 11,714
it's -7 1/3 because since the equation is all negative you would just simply add the -5 and -2 1/3
