Question

How do I find the maximum profit of -30x2+660x-1500

Answer 1

900,000. -30•2= -60 -60+660=600 600•1500=900000

Answer 2

Answer:

2,130

Step-by-step explanation:

1. solve for x.

$x=-\frac{b}{2a}$

when $ax^{2} +bx+c$

$x=\frac{-660)}{2(-30)}\\\\x=\frac{-660)}{-60}\\\\x=11$

2. place value for X into equation

$y=-30x^{2} +660x-1,500\\y=-30(11)^{2} +660(11)-1,500\\y=-30(121)+7,260-1,500\\y=-3,630+7,260-1,500\\y=3,630-1,500\\y=2,130$

Maximim profit is 2,130.
