Fishing Adventures rents small fishing boats to tourists for day‐long fishing trips. Each boat can only carry 1200 pounds of people and gearfor safety reasons. Assume the average weight of a person is 150 pounds. Each group will require 200 lbs of gear for the boat plus 10 lbsof gear for each person.
a. Create an inequality describing the restrictions on the number of people possible in a rented boat. Graph the solution set.
b. Several groups of people wish to rent a boat. Group 1 has 4 people. Group 2 has 5 people. Group 3 has 8 people. Which of thegroups, if any, can safely rent a boat? What is the maximum number of people that may rent a boat?
