A. $54 B. $60 C. $66 D. $100 E. $120 Answer: B Source: Princeton Review IMPORTANT: If Alex received a 10% discount, then Alex PAID 90% of the cost of the books If Victor received a 15% discount, then Victor PAID 85% of the cost of the books Start with a word equation Total amount Alex paid = Total amount Victor paid We get: $12 + 90% of b = $15 + 85% of b Rewrite as: $12 + (0.9)(b) = $15 + (0.85)(b) Eliminate decimals by multiplying both sides by 100 to get: 1200 + 90b = 1500 + 85b Subtract 1200 from both sides: 90b = 300 + 85b Subtract 85b from both sides: 5b = 300 Solve: b = 60 Answer: B Cheers, Brent
