So, you can get the answer by buying the books. What I mean is, you can visualize yourself buying the four books, and adding them together as it goes on. (WITHOUT TAX) You start with 8.95, and multiply it by .75. You do this because once you multiplied it, you don't have to subtract anything, and that would be the value. You would get 6.7125, and just round to the nearest cent. That would be $6.71. Do this to the rest of them, and finally add them together to get the value. To save space, quick fire! 9.55: 7.16, 6.85: 5.14, 12.95: 9.71. Add the values, and the answer is yours. $6.71+$7.16+$5.14+$9.71= 28.72. The answer is $28.72 total sale price. I hope this helps you in anyway, and have a nice day! ( Oh, I ryhmed.)
