Tom spends 30% of his monthly budget on rent. His total monthly budget is $3,000. How much does Tom spend on rent?

The simplest way to do this is (in my opinion; but it is not the only way) to find then answer is to find 10% of his budget and multiply by three. Since he has a budget of $3000, 10% is $300. Multiply it by three to get $900, how much he spends on rent.

30% =.3

3000 x. 3 = 900
