3 boys share some stickers.
Bryan has 40 more than Adam.
Adam has 3 times as many as Charlie.
Bryan and Adam have 500 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 + 40
Number of stickers that Bryan and Adam have is 500 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 500 3 u + 40 + 3 u = 1 u + 500 6 u - 1 u = 500 - 40 5 u = 460
1 u = 460 ÷ 5 = 92 (a)
Number of stickers that Adam has
= 3 x 92
= 276
(b)
Number of stickers that Bryan has
= 3 u + 40
= 3 × 92 + 40
= 276 + 40
= 316
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 40 + 1 u
= 316 + 92
= 408
Answer(s): (a) 276; (b) 316; (c) 408
