Question

The price for a product is given by $p = 4050 - 0.5 x ^ { 2 }$ be sold to give positive revenue?
, where  x  is the number of units sold. How many units must
A) $x < 8100 \text { units }$
B) $x > 90 \text { units }$
C) $0 \text { units } < x < 90 \text { units }$
D) $0 \text { units } < x < 45 \text { units }$

Quizplus · Accepted Answer

Revenue is positive when the price, $p$, is greater than 0. Substituting $p = 4050 - 0.5x^2 > 0$, solving for $x$ gives the range $0 < x < 90$.

The Price for a Product Is Given By p=4050−0.5x2p = 4050 - 0.5 x ^ { 2 }p=4050−0.5x2
