Benjamin Company had the following results of operations for the past year:

Sales (16,000 units at $10)$160,000Direct materials and direct labor$96,000Overhead (20% variable)16,000Selling and administrative expenses (all fixed)32,000(144,000)Operating income$16,000

A foreign company (whose sales will not affect Benjamin's market) offers to buy 4,000 units at $7.50 per unit. In addition to variable manufacturing costs, selling these units would increase fixed overhead by $600 and selling and administrative costs by $300. If Benjamin accepts the offer, its profits will:

Increase by $30,000.

Increase by $6,000.

Decrease by $6,000.

Increase by $5,200.

Increase by $4,300.

Same kind of problem I just had just need to be sure I'm understanding and not making silly math mistakes
