3 buddies share some stickers.
Adam has 90 more than Charlie.
Charlie has 2 times as many as Bryan.
Adam and Charlie have 600 more than Bryan.
- How many stickers does Charlie have?
- How many stickers does Adam have?
- How many stickers do Adam and Bryan have?
Choose the person with least stickers to be 1 u.
Number of stickers that Bryan has = 1 u
Number of stickers that Charlie has = 2 u
Number of stickers that Adam has = 2 u + 90
Number of stickers that Adam and Charlie have is 600 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 600 2 u + 90 + 2 u = 1 u + 600 4 u - 1 u = 600 - 90 3 u = 510
1 u = 510 ÷ 3 = 170 (a)
Number of stickers that Charlie has
= 2 x 170
= 340
(b)
Number of stickers that Adam has
= 2 u + 90
= 2 × 170 + 90
= 340 + 90
= 430
(c)
Number of stickers that Adam and Bryan have
= 2 u + 90 + 1 u
= 430 + 170
= 600
Answer(s): (a) 340; (b) 430; (c) 600
