Horngren's managerial chapters-12 edition Chapter 20 S20-3 Calculating conversion costs

Bananarama Plum Manufactures a juice blend. last month's total manufacturing costs for the Jupiter, FL operation included:

Direct materials $450,000

Direct labor 32,000

Manufacturing overhead 125,000

What was the conversion cost for Bananarama Plum's Jupiter operation last month?

Solution: Need to check if this is right

Conversion costs	=	Direct labor	+	Manufacturing Overhead
	=	answer here/ my guess (32,000)	+	answer here/my guess (450,000)
	=	answer here/ my guess (125,000)

I am all mixed up when it comes to conversions costs any help will do.
