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.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
