Adam has 60 more than Charlie.
Charlie has 5 times as many as Bryan.
Adam and Charlie have 600 more than Bryan.
- How many stickers does Charlie have?
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have?
Choose the person with least stickers to be 1 u.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 5 u
Number of stickers that Adam has = 5 u + 60
Number of stickers that Adam and Charlie have is 600 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 600 5 u + 60 + 5 u = 1 u + 600 10 u - 1 u = 600 - 60 9 u = 540
1 u = 540 ÷ 9 = 60 (a)
Number of stickers that Charlie has
= 5 x 60
= 300
(b)
Number of stickers that Adam has
= 5 u + 60
= 5 × 60 + 60
= 300 + 60
= 360
(c)
Number of stickers that Adam and Bryan have
= 5 u + 60 + 1 u
= 360 + 60
= 420
Answer(s): (a) 300; (b) 360; (c) 420
