3 boys share some stickers.
Bryan has 70 more than Charlie.
Charlie has 3 times as many as Adam.
Bryan and Charlie have 500 more than Adam.
- How many stickers does Charlie have?
- How many stickers does Bryan have?
- How many stickers do Bryan and Adam have?
Choose the person with least stickers to be 1 u.
Number of stickers that Adam has = 1 u
Number of stickers that Charlie has = 3 u
Number of stickers that Bryan has = 3 u + 70
Number of stickers that Bryan and Charlie have is 500 more than Adam.
Number
of stickers that Bryan and Charlie have = 1 u + 500 3 u + 70 + 3 u = 1 u + 500 6 u - 1 u = 500 - 70 5 u = 430
1 u = 430 ÷ 5 = 86 (a)
Number of stickers that Charlie has
= 3 x 86
= 258
(b)
Number of stickers that Bryan has
= 3 u + 70
= 3 × 86 + 70
= 258 + 70
= 328
(c)
Number of stickers that Bryan and Adam have
= 3 u + 70 + 1 u
= 328 + 86
= 414
Answer(s): (a) 258; (b) 328; (c) 414
