3 buddies share some stickers.
Adam has 80 more than Bryan.
Bryan has 2 times as many as Charlie.
Adam and Bryan have 500 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 = 2 u
Number of stickers that Adam has = 2 u + 80
Number of stickers that Adam and Bryan have is 500 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 500 2 u + 80 + 2 u = 1 u + 500 4 u - 1 u = 500 - 80 3 u = 420
1 u = 420 ÷ 3 = 140 (a)
Number of stickers that Bryan has
= 2 x 140
= 280
(b)
Number of stickers that Adam has
= 2 u + 80
= 2 × 140 + 80
= 280 + 80
= 360
(c)
Number of stickers that Adam and Charlie have
= 2 u + 80 + 1 u
= 360 + 140
= 500
Answer(s): (a) 280; (b) 360; (c) 500
