Gwen has 13 stamps fewer than Vanessa but 49 stamps more than Bobby. The three children have 207 stamps altogether.
- How many stamps does Bobby have?
- How many stamps does Vanessa have?
(a)
Number of stamps Vanessa has = 1 u
Number of stamps Gwen has = 1 u - 13
Number of stamps Bobby has = 1 u - 13 - 49 = 1 u - 62
Total number of stamps
= 1 u + 1 u - 13 + 1 u - 62
= 3 u - 75
3 u - 75 = 207
3 u = 207 + 75
3 u = 282
1 u = 282 ÷ 3 = 94
Number of stamps that Bobby has
= 1 u - 62
= 94 - 62
= 32
(b)
Number of stamps that Vanessa has
= 1 u
= 94
Answer(s): (a) 32; (b) 94
