7.EE Fishing Adventures 2
Alignment 1: 7.EE.B.4
Fishing Adventures rents small fishing boats to tourists for day‐long fishing trips.
Each boat can only carry 1200 pounds of people and gear
for 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 lbs
of 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 the
groups, if any, can safely rent a boat? What is the maximum number of people that
may rent a boat?
