Answer:
$522.12
Explanation:
We can find this by x=-b/(2a) where a = -2 and b = 105:
x = -105/(2)(-2)
x= -105/-4
x= 105/4
We put this value of "x" into the original formula to find out the value of "y"
y = -2x^2 + 105x - 859
y = (-2)(105/4)^2 + 105(105/4) - 859
y = -1378.13 + 2756.25 - 859
y = 522.12
Therefore, the maximum profit would be $522.12
Hope this helps!!
