3 buddies share some stickers.
Bryan has 60 more than Adam.
Adam has 3 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 = 3 u
Number of stickers that Bryan has = 3 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 3 u + 60 + 3 u = 1 u + 300 6 u - 1 u = 300 - 60 5 u = 240
1 u = 240 ÷ 5 = 48 (a)
Number of stickers that Adam has
= 3 x 48
= 144
(b)
Number of stickers that Bryan has
= 3 u + 60
= 3 × 48 + 60
= 144 + 60
= 204
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 60 + 1 u
= 204 + 48
= 252
Answer(s): (a) 144; (b) 204; (c) 252
