Question

Nicholas bought three business related books. His total bill was $150. If one book cost him 50% more than the other two books combined what was the price of this more expensive book? $80.00 $85.00 $90.00 $95.00 $100.00

Answer 1

The price of this more expensive book was $90.00 ($150 - $60) based on the date acquired from the question above. This problem can be solved using a simple algebra equation which consisted of one variable. The equation is stated as $150 = x + 1.5x (x = $150/2.5 = $60) where x is the price of the cheaper book and 1.5x is the price of the more expensive books because it has 50% higher price than the cheaper book.
