3 children share some stickers.
Adam has 90 more than Bryan.
Bryan has 3 times as many as Charlie.
Adam and Bryan have 500 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 = 3 u
Number of stickers that Adam has = 3 u + 90
Number of stickers that Adam and Bryan have is 500 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 500 3 u + 90 + 3 u = 1 u + 500 6 u - 1 u = 500 - 90 5 u = 410
1 u = 410 ÷ 5 = 82 (a)
Number of stickers that Bryan has
= 3 x 82
= 246
(b)
Number of stickers that Adam has
= 3 u + 90
= 3 × 82 + 90
= 246 + 90
= 336
(c)
Number of stickers that Adam and Charlie have
= 3 u + 90 + 1 u
= 336 + 82
= 418
Answer(s): (a) 246; (b) 336; (c) 418
