3 brothers share some stickers.
Bryan has 70 more than Charlie.
Charlie has 4 times as many as Adam.
Bryan and Charlie have 700 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 = 4 u
Number of stickers that Bryan has = 4 u + 70
Number of stickers that Bryan and Charlie have is 700 more than Adam.
Number
of stickers that Bryan and Charlie have = 1 u + 700 4 u + 70 + 4 u = 1 u + 700 8 u - 1 u = 700 - 70 7 u = 630
1 u = 630 ÷ 7 = 90 (a)
Number of stickers that Charlie has
= 4 x 90
= 360
(b)
Number of stickers that Bryan has
= 4 u + 70
= 4 × 90 + 70
= 360 + 70
= 430
(c)
Number of stickers that Bryan and Adam have
= 4 u + 70 + 1 u
= 430 + 90
= 520
Answer(s): (a) 360; (b) 430; (c) 520
