Answer:
The first set of expenses is 75% of the second assuming we are in a 30-day month.
Step-by-step explanation:
To find this, we first have to find out how much we spend a month in coffee. To do so, we multiply the daily cost by number of days in a month (we'll use 30 for this case).
$3 * 30 days = $90 a month.
Now to find the percentage, we divide what we spend in coffee by what we spend on gas.
$90/$120 = 75%
