Answer:
They will need 197 canoes.
Step-by-step explanation:
The first step is to find the ''3-people canoes'' that they filled.
Given that 273 people filled a certain number ''a'' of canoes that each hold 3 people, we know that is we multiply the number of canoes ''a'' by the number of people that can each canoe hold, we will obtain the number of people who
will take the canoe trip in the ''3-people canoes''. We write :

We find that canoes. This means that 91 ''3-people canoes'' were filled each one with 3 people in order to hold 273 people in total.
The second step is to find the remaining people that won't take the ''3-people canoes''. We do this by subtracting 273 people to the total 485 people.
We know that 212 people will travel in the ''2-people canoes''. Using a similar reasoning and defining as ''b'' to the total number of ''2-people canoes'' we write :
We find that canoes is the total number of ''2-people canoes'' that we need If we want them to be filled up with 212 people.
