What is Sally’s greatest single expense?
Drupady [299]

Answer:

Room and board

30%

Step-by-step 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.
