3 children share some stickers.
Bryan has 80 more than Adam.
Adam has 3 times as many as Charlie.
Bryan and Adam have 200 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 + 80
Number of stickers that Bryan and Adam have is 200 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 200 3 u + 80 + 3 u = 1 u + 200 6 u - 1 u = 200 - 80 5 u = 120
1 u = 120 ÷ 5 = 24 (a)
Number of stickers that Adam has
= 3 x 24
= 72
(b)
Number of stickers that Bryan has
= 3 u + 80
= 3 × 24 + 80
= 72 + 80
= 152
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 80 + 1 u
= 152 + 24
= 176
Answer(s): (a) 72; (b) 152; (c) 176
