A retailer purchased 100 pairs of pants from a new vendor.  The original retail price for these pants was set at $14.00 each, and 70 pairs were sold at this price.  Then, the first markdown to $10.00 per pair resulted in the sale of another 25 pairs.  Finally, the remaining 5 pairs were once again marked down to $8.00 and all sold at the second markdown price.  Please answer Q39 – Q40.   What was the markdown% for the first markdown?
