3 children share some stickers.
Adam has 50 more than Bryan.
Bryan has 4 times as many as Charlie.
Adam and Bryan have 400 more than Charlie.
- How many stickers does Bryan have?
- How many stickers does Adam have?
- How many stickers do Adam 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 Bryan has = 4 u
Number of stickers that Adam has = 4 u + 50
Number of stickers that Adam and Bryan have is 400 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 400 4 u + 50 + 4 u = 1 u + 400 8 u - 1 u = 400 - 50 7 u = 350
1 u = 350 ÷ 7 = 50 (a)
Number of stickers that Bryan has
= 4 x 50
= 200
(b)
Number of stickers that Adam has
= 4 u + 50
= 4 × 50 + 50
= 200 + 50
= 250
(c)
Number of stickers that Adam and Charlie have
= 4 u + 50 + 1 u
= 250 + 50
= 300
Answer(s): (a) 200; (b) 250; (c) 300
