3 children share some stickers.
Adam has 10 more than Bryan.
Bryan has 5 times as many as Charlie.
Adam and Bryan have 100 more than Charlie.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers do Adam and Charlie have?
Choose the person with least stickers to be 1 u.
Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 5 u
Number of stickers that Adam has = 5 u + 10
Number of stickers that Adam and Bryan have is 100 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 100 5 u + 10 + 5 u = 1 u + 100 10 u - 1 u = 100 - 10 9 u = 90
1 u = 90 ÷ 9 = 10 (a)
Number of stickers that Bryan has
= 5 x 10
= 50
(b)
Number of stickers that Adam has
= 5 u + 10
= 5 × 10 + 10
= 50 + 10
= 60
(c)
Number of stickers that Adam and Charlie have
= 5 u + 10 + 1 u
= 60 + 10
= 70
Answer(s): (a) 50; (b) 60; (c) 70
