4x = 17+5
x = 22/4
x = 11/2 = 5.5
Answer:
$3, $11
Step-by-step explanation:
The profit function P(x) will be zero when either of its factors is zero. The left factor (x-3) is zero when x=3. The right factor (x-11) is zero when x=11.
Prices of $3 or $11 will result in $0 annual profit.
_____
<em>Additional comment</em>
A price halfway between these values, at (3+11)/2 = 7, will produce maximum profit, $32 million.
I think it would be 4? cause then it would give you .25
