> say the books value is 7.5, Mash must have 1.5 (7.5 - 7) and Misha 6.5 (7.5 - 1), however now when you combine them they sum to exactly 7.5 not less than There are several problems with this: - 7.5 - 7 is 0.5, not 1.5 - 1.5 + 6.5 is 8, not 7.5 - 0.5 + 6.5 is still less than 7.5 The problem specifies that 2x - 8 < x. There is no way to constrain this to the specific solution x = 7. Everything would work fine if the book cost -2.6 kopecks. |
