Adam has 50 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 + 50
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 + 50 + 3 u = 1 u + 500 6 u - 1 u = 500 - 50 5 u = 450
1 u = 450 ÷ 5 = 90 (a)
Number of stickers that Bryan has
= 3 x 90
= 270
(b)
Number of stickers that Adam has
= 3 u + 50
= 3 × 90 + 50
= 270 + 50
= 320
(c)
Number of stickers that Adam and Charlie have
= 3 u + 50 + 1 u
= 320 + 90
= 410
Answer(s): (a) 270; (b) 320; (c) 410
