3 buddies share some stickers.
Bryan has 90 more than Adam.
Adam has 3 times as many as Charlie.
Bryan and Adam have 300 more than Charlie.
- How many stickers does Adam have?
- How many stickers does Bryan have?
- How many stickers do Bryan 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 Adam has = 3 u
Number of stickers that Bryan has = 3 u + 90
Number of stickers that Bryan and Adam have is 300 more than Charlie.
Number
of stickers that Bryan and Adam have = 1 u + 300 3 u + 90 + 3 u = 1 u + 300 6 u - 1 u = 300 - 90 5 u = 210
1 u = 210 ÷ 5 = 42 (a)
Number of stickers that Adam has
= 3 x 42
= 126
(b)
Number of stickers that Bryan has
= 3 u + 90
= 3 × 42 + 90
= 126 + 90
= 216
(c)
Number of stickers that Bryan and Charlie have
= 3 u + 90 + 1 u
= 216 + 42
= 258
Answer(s): (a) 126; (b) 216; (c) 258
