4.)A travel agency will plan a group tour for groups of size30or larger. If the group contains exactly 30 people, the cost is$380per person. If each person's cost is reduced by $10 for each additional person above the 30, then the revenue is given by the equation shown below, wherexis the number of additional people above 30.
R(x) = (30 +x)(38010x)
Find the marginal revenue if the group contains35people.
