3 buddies share some stickers.
Bryan has 60 more than Adam.
Adam has 2 times as many as Charlie.
Bryan and Adam have 300 more than Charlie.
- How many stickers does Adam have?
- How many stickers does Bryan have?
- How many stickers do Bryan 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 Adam has = 2 u
Number of stickers that Bryan has = 2 u + 60
Number of stickers that Bryan and Adam have is 300 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 300 2 u + 60 + 2 u = 1 u + 300 4 u - 1 u = 300 - 60 3 u = 240
1 u = 240 ÷ 3 = 80 (a)
Number of stickers that Adam has
= 2 x 80
= 160
(b)
Number of stickers that Bryan has
= 2 u + 60
= 2 × 80 + 60
= 160 + 60
= 220
(c)
Number of stickers that Bryan and Charlie have
= 2 u + 60 + 1 u
= 220 + 80
= 300
Answer(s): (a) 160; (b) 220; (c) 300
