Helen [10]
Manufacturing cost = $136
sellers added 25% = $ 136 * 25/100 = $34 
manufacturers cost + 25% = $136 + $34 = $170. 
old selling price = $170

Sellers decreased the markup to 17% (of manufacturing cost): $136 x 17/100  = $23.12
New selling price = $136 + $23.12 = $153.12

both of these answers show: original cost + markup value
