My question is: Each purple book has 230 pages. Each orange book contains 510 pages. Mirella read 5 purple books and 4 orange books. How many more orange pages did she read than purple pages? Your thoughts:
Purple = 5 * 230 = 1150 pages. Orange = 4 * 510 = 2040 pages. 2040 - 1150 = 890. Mirella read 890 more orange pages than purple pages. The final answer: 890.
