A travel agency will plan a group tour for groups of size 40 or larger. 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. $ Interpret your result. O The revenue will increase by the absolute value of the marginal revenue in dollars if the group adds one person. O The revenue will decrease by the absolute value of the marginal revenue in dollars if the group adds one person. O The revenue will decrease by $1 if the group adds the absolute value of the marginal revenue number of people. O The revenue will increase by $1 if the group adds the absolute value of the marginal revenue number of people. O The revenue will decrease by the absolute value of the marginal revenue in dollars if the group removes one person.

Question
A travel agency will plan a group tour for groups of size 40 or larger. 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.
$
Interpret your result.
O The revenue will increase by the absolute value of the marginal revenue in dollars if the group adds one person.
O The revenue will decrease by the absolute value of the marginal revenue in dollars if the group adds one person.
O The revenue will decrease by $1 if the group adds the absolute value of the marginal revenue number of people.
O The revenue will increase by $1 if the group adds the absolute value of the marginal revenue number of people.
O The revenue will decrease by the absolute value of the marginal revenue in dollars if the group removes one person.
