The revenue for selling q items is $R(q)=600 q-2 q^{2}$ and the total cost is C(q)= 110 + 60q.Which function gives the total profit earned?
A) $-540 q+2 q^{2}+110$
B) $-540 q+2 q^{2}-110$
C) $540 q-2 q^{2}+110$
D) $540 q-2 q^{2}-110$

Question

Quizplus · Accepted Answer

Profit is calculated as Revenue minus Cost. So, $P(q) = R(q) - C(q) = (600q - 2q^2) - (110 + 60q) = 540q - 2q^2 - 110$.

The Revenue for Selling Q Items Is R(q)=600q−2q2R(q)=600 q-2 q^{2}R(q)=600q−2q2 And the Total Cost Is C(q)= 110 + 60q

The Revenue for Selling Q Items Is $R(q)=600 q-2 q^{2}$ And the Total Cost Is C(q)= 110 + 60q
