The Fishman family income for one month is $2,000. If 25% is spent for lodging, 35% for food, 5% for clothing, and 10% for savings, how many dollars are left for other expenses?

We first need to see how much the percents are which looks like this:

35 + 25 + 5 + 10 = 75

So already we know that the costs add up to only 75% of 100%. We then can subtract 100 from 75 which is 25. We then can just find what 25 percent of 2,000 is, which is 500.

500 dollars are left for other expenses.
