If the unit selling price is 2.50 and the unit cost is 1.00 what action is needed to maintain the gross margin percentage when unit cost increase 0.25

The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5  =  150%

the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%

  in order to keep the same gross margin, you need to increase the sale price by 25%

2.50*1.25 = 3.125

Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )
