3 boys share some stickers.
Bryan has 50 more than Charlie.
Charlie has 3 times as many as Adam.
Bryan and Charlie have 800 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 + 50
Number of stickers that Bryan and Charlie have is 800 more than Adam.
Number
of stickers that Bryan and Charlie have = 1 u + 800 3 u + 50 + 3 u = 1 u + 800 6 u - 1 u = 800 - 50 5 u = 750
1 u = 750 ÷ 5 = 150 (a)
Number of stickers that Charlie has
= 3 x 150
= 450
(b)
Number of stickers that Bryan has
= 3 u + 50
= 3 × 150 + 50
= 450 + 50
= 500
(c)
Number of stickers that Bryan and Adam have
= 3 u + 50 + 1 u
= 500 + 150
= 650
Answer(s): (a) 450; (b) 500; (c) 650
