Does Raising or Lowering Price Earn More

On a $50 item costing $30 with 1,000 units sold, your current profit is $20,000. Raising price 10% and losing 15% of volume drops profit to $18,700, while lowering price 10% and gaining 20% volume raises profit to $21,600. In this case the discount wins. The result flips with different elasticity, so plug in your own numbers.
