Kathy has 7 stamps fewer than Jaslyn but 48 stamps more than Vaidev. The three children have 289 stamps altogether.
- How many stamps does Vaidev have?
- How many stamps does Jaslyn have?
(a)
Number of stamps Jaslyn has = 1 u
Number of stamps Kathy has = 1 u - 7
Number of stamps Vaidev has = 1 u - 7 - 48 = 1 u - 55
Total number of stamps
= 1 u + 1 u - 7 + 1 u - 55
= 3 u - 62
3 u - 62 = 289
3 u = 289 + 62
3 u = 351
1 u = 351 ÷ 3 = 117
Number of stamps that Vaidev has
= 1 u - 55
= 117 - 55
= 62
(b)
Number of stamps that Jaslyn has
= 1 u
= 117
Answer(s): (a) 62; (b) 117
