A certain canoe was advertised as having an "800 pound capacity," meaning that it can hold at most 800 pounds. If four people plan to use the canoe and take 60 pounds of supplies, write and solve an inequality to find the average weight per person.

let x be the average weight per person

4x + 60 ≤ 800
x ≤ 185

(Wow, as a canoeist I must tell you this is an absurd question.
Four 185 pounders and gear in one canoe ???
What is this, a 17th century voyageur canoe? )

At most is represented by using the symbol Ём, which stands for less than or equal to.

We can use any letter to represent the average weight for each person.

I will use W.

800 Ём 4 times W and 60 pounds of supplies

800 Ём 4W + 60

800 - 60 Ём 4W

740 Ём 4W

740/4 Ём W

185 Ём W
