3 children share some stickers.
Adam has 30 more than Charlie.
Charlie has 3 times as many as Bryan.
Adam and Charlie have 900 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 = 3 u
Number of stickers that Adam has = 3 u + 30
Number of stickers that Adam and Charlie have is 900 more than Bryan.
Number
of stickers that Adam and Charlie have = 1 u + 900 3 u + 30 + 3 u = 1 u + 900 6 u - 1 u = 900 - 30 5 u = 870
1 u = 870 ÷ 5 = 174 (a)
Number of stickers that Charlie has
= 3 x 174
= 522
(b)
Number of stickers that Adam has
= 3 u + 30
= 3 × 174 + 30
= 522 + 30
= 552
(c)
Number of stickers that Adam and Bryan have
= 3 u + 30 + 1 u
= 552 + 174
= 726
Answer(s): (a) 522; (b) 552; (c) 726
