Overall, this is equivalent to what reduction on the original prices?</mdoxml> <?xml version="1.0" encoding="UTF-8"?> <mdoxml version="1.0">The reduction of 15% off sale prices is equal to a reduction of 7.5% off the original prices. Therefore the toal reduction on the original prices is (50 + 7.5)% = 57.5%.</mdoxml> 2 3 0 0 1 0 0 Weekly Problem 11 - 2013
