If you put the dollar decrease as x, you sell charge<span>
16−x</span>
dollars and sell<span>
92+4x</span>
units for a profit of<span>
(16−x)(92+4x)−(2+4x)</span>
dollars. the last subtraction because your cost is $1 per unit multiply out and
get<span>
P=−4<span>x2</span>−32x+1470</span>
which will have a maximum at the vertex<span><span>
x=−<span>b/<span>2a
</span></span>= <span><span>32/(</span><span>2(−4))
</span></span>
= −4
