The correct option will be: B. 29%
Explanation
Total yearly office supply budget is $1200 and the amount spent each year on paper is $350.
For finding the percentage of paper, we will first divide the amount spent on paper by the total budget and then multiply by 100%
So, the percentage of paper [tex]= \frac{350}{1200}*100 = \frac{350}{12}= 29.1666...[/tex] % ≈ 29 %
So, 29% of your budget, you spend on paper.
