Answer:
Room and board
30%
Explanation:
If you look at the numbers in the table, you can easily see Room and board is the largest expense, with $127.50, three times more than the second place.
Now, to find the percent of that expense vs her income we just have to divide this big expense ($127.50) by the total income she has ($425).
% = $127.50 / $425 = 30%
So, that expense is 30% of her income, that's a big chunk, but it's normal for lodging expenses.
