Answer: Let's use algebra to solve the problem.
Let x be the number of candy bars Landon bought. We know that:
The cost of the magazine is $5.
The cost of x candy bars is 3x dollars.
The total cost is $23.
We can use these pieces of information to set up an equation:
5 + 3x = 23
Subtracting 5 from both sides, we get:
3x = 18
Dividing both sides by 3, we get:
x = 6
Therefore, Landon bought 6 candy bars.
