PRACTICE ANOTHER Minimizing Construction Costs The management of the UNICO department store has decided to enclose a 942 2 area outside the building for displaying potted plants and owers. One side will be formed by the external wall of the store, two sides will be constructed of pine boards, and the fourth side will be made of galvanized steel fencing. If the pine board fencing costs $7/running foot and the steel fencing costs $4/running foot, determine the dimensions of the enclosure that can be erected at minimum cost. (Round your answers to one decimal place.) FF wood side steel side : 2. [-/3 Points] TANAPCALC10 4.5.019. PRACTICE ANOTHER Optimal Chapter-Flight Fare If exactly 182 people sign up for a charter ight, Leisure World Travel Agency charges $302/person. However, if more than 182 people sign up for the ight (assume this is the case), then each fare is reduced by $1 for each additional person. Determine how many passengers will result in a maximum revenue for the travel agency. Hint: Let x denote the number of passengers above 182. Show that the revenue function R is given by R(x) = (182 + x)(302 x). passengers What is the maximum revenue? $ :1 What would be the fare per passenger in this case? :] dollars per passenger 3.

PRACTICE ANOTHER Charter Revenue The owner of a luxury motor yacht that sails among the 4000 Greek islands charges $720/person/day if exactly 20 people sign up for the cruise. However, if more than 20 people sign up (up to the maximum capacity of 100) for the cruise, then each fare is reduced by $8 for each additional passenger. Assuming at least 20 people sign up for the cruise, determine how many passengers will result in the maximum revenue for the owner of the yacht. passengers What is the maximum revenue? $ What would be the fare/passenger in this case?
