There are four lamps in Valerie's room. All of them are burnt out, so she needs to buy new light bulbs. She needs 3 small light bulbs and 1 large light bulb. She has $60 to spend. If small light bulbs cost $8 and large light bulbs cost $12, how much money will Valerie have left over? Let's be accurate as possible.

She will spend 3 * $8 = $24 on small light bulbs. In total she will spend $24 + $12 = $36 on the 4 light bulbs. She will have $60 - $36 = $24 left over.
The answer: 24.
