Textbook U has 88 fewer pages than Textbook V, and Textbook W has 26 more pages than Textbook V. If Textbook U and Textbook V have a total of 212 pages,
- how many pages does Textbook V have?
- how many pages does Textbook W have?
(a)
Number of pages that Textbook U has = 1 u
Number of pages that Textbook V has = 1 u + 88
Number of pages that Textbook W has = 1 u + 88 + 26
Total number of pages that Textbook U and Textbook V have
= 1 u + 1 u + 88
= 2 u + 88
2 u + 88 = 212
2 u = 212 - 88
2 u = 124
1 u = 124 ÷ 2 = 62
Number of pages that Textbook V has
= 1 u + 88
= 62 + 88
= 150
(b)
Number of pages that Textbook W has
= 1 u + 88 + 26
= 150 + 26
= 176
Answer(s): (a) 150; (b) 176
