Adam has 70 more than Bryan.
Bryan has 3 times as many as Charlie.
Adam and Bryan have 700 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 + 70
Number of stickers that Adam and Bryan have is 700 more than Charlie.
Number
of stickers that Adam and Bryan have = 1 u + 700 3 u + 70 + 3 u = 1 u + 700 6 u - 1 u = 700 - 70 5 u = 630
1 u = 630 ÷ 5 = 126 (a)
Number of stickers that Bryan has
= 3 x 126
= 378
(b)
Number of stickers that Adam has
= 3 u + 70
= 3 × 126 + 70
= 378 + 70
= 448
(c)
Number of stickers that Adam and Charlie have
= 3 u + 70 + 1 u
= 448 + 126
= 574
Answer(s): (a) 378; (b) 448; (c) 574
