3 children have 1700 stickers.
Adam has 200 more than Bryan
but 1000 less than Charlie.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers does Charlie have?
Choose the person with least stickers to be 1 u.
Number of stickers that Bryan has = 1 u
Number of stickers that Adam has = 1 u + 200
Number of stickers that Charlie has = 1 u + 200 + 1000 = 1 u + 1200
Total number of stickers
= 1 u + 1 u + 200 + 1 u + 1200
= 3 u + 1400
3 u + 1400 = 1700
3 u = 1700 - 1400
3 u = 300
1 u = 300 ÷ 3 = 100
(a)
Number of stickers that Bryan has
= 1 u
= 100
(b)
Number of stickers that Adam has
= 1 u + 200
= 100 + 200
= 300
(c)
Number of stickers that Charlie has
= 1 u + 1200
= 100 + 1200
= 1300
Answer(s): (a) 100; (b) 300; (c) 1300
