Assuming the bullet points are not negative signs....
Look at the first part of the phrase:
"Five more than three times the number"
The variable 'n' would represent "the number."
Three times the number would be 3n.
Five more than that would be 3n+5.
Now look at the second part of the phrase:
"one third more than the sum of the number and itself."
This is a bit tricky. (Didn't quite understand this, so I had to look at the four possible answers.)
I assume "the sum of the number and itself" is n+n.
And 1/3 more than that would simply be (n+n) + 1/3.
Now using the 'equal' sign let's put these two parts together. (No, we are not adding)
3n+5=(n+n)+1/3
And that is the fourth answer.
So the fourth answer is correct.
(This was a tricky question...especially because I spent a lot of time wondering if those bullet points were negative signs)
