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