3 children share some stickers.
Bryan has 40 more than Adam.
Adam has 4 times as many as Charlie.
Bryan and Adam have 600 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 = 4 u
Number of stickers that Bryan has = 4 u + 40
Number of stickers that Bryan and Adam have is 600 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 600 4 u + 40 + 4 u = 1 u + 600 8 u - 1 u = 600 - 40 7 u = 560
1 u = 560 ÷ 7 = 80 (a)
Number of stickers that Adam has
= 4 x 80
= 320
(b)
Number of stickers that Bryan has
= 4 u + 40
= 4 × 80 + 40
= 320 + 40
= 360
(c)
Number of stickers that Bryan and Charlie have
= 4 u + 40 + 1 u
= 360 + 80
= 440
Answer(s): (a) 320; (b) 360; (c) 440
