Adam has 50 more than Charlie.
Charlie has 2 times as many as Bryan.
Adam and Charlie have 500 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 = 2 u
Number of stickers that Adam has = 2 u + 50
Number of stickers that Adam and Charlie have is 500 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 500 2 u + 50 + 2 u = 1 u + 500 4 u - 1 u = 500 - 50 3 u = 450
1 u = 450 ÷ 3 = 150 (a)
Number of stickers that Charlie has
= 2 x 150
= 300
(b)
Number of stickers that Adam has
= 2 u + 50
= 2 × 150 + 50
= 300 + 50
= 350
(c)
Number of stickers that Adam and Bryan have
= 2 u + 50 + 1 u
= 350 + 150
= 500
Answer(s): (a) 300; (b) 350; (c) 500
