Darien Industries operates a cafeteria for its employees. The operation of the cafeteria requires fixed costs of $4,700 per month and variable costs of 40 percent of sales. The average cafeteria sales are currently $12,000 per month. Darien has an opportunity to replace the cafeteria with vending machines. Gross customer spending at vending machines is estimated to be 40 percent greater than current sales because the machines are available at all hours. By replacing the cafeteria with vending machines, Darien would avoid all cafeteria costs but receive 16 percent of the gross customer spending. How much does monthly operating income change if Darien Industries replaces the cafeteria with vending machines?
