A) 116
B) 126
C) 136
D) 416
E) 146
Correct Answer: D
Solution :
Given, \[R(x)=13{{x}^{2}}+26x+15\] Now, the marginal revenue \[=\frac{d}{dx}(R(x))\] \[=\frac{d}{dx}(13{{x}^{2}}+26x+15)\] \[=26x+26\] Therefore, marginal revenue at \[(x=15)\] \[=26\times 15+26\] \[=390+26=416\]You need to login to perform this action.
