 Ans:-

C(x)=0.02x+50,C'(x) = -0.02x + 50, forx800for x ≤ 800

integrating the above equation

C(x)=0.02x+50\Rightarrow \int C'(x)=\int-0.02x+50


C(x)=0.01x2+50x\Rightarrow C(x)=-0.01x^2+50x


to find the total cost, in dollars, of producing 550 cards then put x=550x=550


C(550)=0.01(550)2+50×550=24475C(550)=-0.01(550)^2+50\times550=24475 $
