should best board make or buy the wakeboards under this bid?

Best Boards, Inc. produces each wakeboard for $110 each and Jim Muller, vice president of operations, received a bid for $70 per board from an outside manufacturer. The variable production costs are $56 each and the fixed production costs are $540,000 for 10,000 units each year. If the wakeboards were to be purchased, the company would save on variable productions costs and $50,000 on the fixed production costs but all other fixed costs would remain.
