Notice that total weight of four people plus the weight of the supply must be no more than the capacity of the canoe.
Inequality: 4n+60≤ 800 Solution: n ≤ 185
Practice makes perfect
We are given a canoe with an 800-lb capacity. This means that we need the total weight in the canoe to be less than or equal to 800 lb. To show this, we can use a non-strict inequality.
... ≤ 800Four people plan to use the canoe and they will bring 60 pounds of supplies. We want to write an inequality to find the allowable average weight per person. Let n represent the average weight of a person. We can now write the inequality algebraically by considering that total weight of four people plus the weight of the supply must be no more than the capacity of the canoe.
4 n+ 60≤ 800
From here, since we wrote our inequality, we can solve this inequality for n.
