Please answer all the questions clearly.

1. Robinson Computers makes 5,700 units of a circuit board, CB76 at a cost of $230 each. Variable cost per unit is $180 and fixed cost per unit is $50. Peach Electronics offers to supply 5,700 units of CB76 for $210. If Robinson buys from Peach it will be able to save $20 per unit in fixed costs but continue to incur the remaining $30 per unit. Should Robinson accept Peach's offer? Explain. 2. RT Manufacturing is deciding whether to keep or replace an old machine.
