Tiffany has 6 stickers fewer than Jean but 19 stickers more than Vincent. The three children have 143 stickers altogether.
- How many stickers does Vincent have?
- How many stickers does Jean have?
(a)
Number of stickers Jean has = 1 u
Number of stickers Tiffany has = 1 u - 6
Number of stickers Vincent has = 1 u - 6 - 19 = 1 u - 25
Total number of stickers
= 1 u + 1 u - 6 + 1 u - 25
= 3 u - 31
3 u - 31 = 143
3 u = 143 + 31
3 u = 174
1 u = 174 ÷ 3 = 58
Number of stickers that Vincent has
= 1 u - 25
= 58 - 25
= 33
(b)
Number of stickers that Jean has
= 1 u
= 58
Answer(s): (a) 33; (b) 58
