3 cousins share some stickers.
Adam has 10 more than Bryan.
Bryan has 4 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 = 4 u
Number of stickers that Adam has = 4 u + 10
Number of stickers that Adam and Bryan have is 500 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 500 4 u + 10 + 4 u = 1 u + 500 8 u - 1 u = 500 - 10 7 u = 490
1 u = 490 ÷ 7 = 70 (a)
Number of stickers that Bryan has
= 4 x 70
= 280
(b)
Number of stickers that Adam has
= 4 u + 10
= 4 × 70 + 10
= 280 + 10
= 290
(c)
Number of stickers that Adam and Charlie have
= 4 u + 10 + 1 u
= 290 + 70
= 360
Answer(s): (a) 280; (b) 290; (c) 360
