What is correct answer?

A rotavonal molding operation has fixed costs of $5,000 per year and vartable costs of $52 per unit. If the process is autornated via corveyor, is fixed cost will be $57,000 per year, but its varlable cost will be only $10 per unit. Determine the number of units each year necessary for the two operaelons to break even. The number of units each year necessary for the two operations to break even is determined to be
