Question 1160495
Step 1 - Find total weight of people and backpacks


Adults - (160)(2) = 320 lbs.
Scouts - (100)(8) = 800 lbs.
Backpacks - (20)(10) = 200 lbs.
Total - 320 + 800 + 200 = 1320 lbs.



Step 2 - Find number of boats needed


1320/360 = 3.6 repeating

You can't have .6 of a boat, so round up to 4.


Final Answer: 4 boats
