If the group contains exactly 40 people, the cost is $340 per person. If each person's cost is reduced by $10 for each additional person above the 40, then the revenue is given by the equation shown below, where x is the number of additional people above 40. R(x) (40 x)(340- 10x) Find the marginal revenue if the group contains 45 people 13440X Need Help? Read It Watch It Talk to a Tutor

Explanation / Answer

R(x)= (40+x)(340+10x)

R(x)=10x2+740x+13600

Marginal revenue, R'(x) = 10(2)x +740 = 20 x +740 = 20(45)+740= 900+740=1640
