Kylie has 12 stamps fewer than Penelope but 17 stamps more than John. The three children have 238 stamps altogether.
- How many stamps does John have?
- How many stamps does Penelope have?
(a)
Number of stamps Penelope has = 1 u
Number of stamps Kylie has = 1 u - 12
Number of stamps John has = 1 u - 12 - 17 = 1 u - 29
Total number of stamps
= 1 u + 1 u - 12 + 1 u - 29
= 3 u - 41
3 u - 41 = 238
3 u = 238 + 41
3 u = 279
1 u = 279 ÷ 3 = 93
Number of stamps that John has
= 1 u - 29
= 93 - 29
= 64
(b)
Number of stamps that Penelope has
= 1 u
= 93
Answer(s): (a) 64; (b) 93
