Glen has five times as many stickers as Ken. Ken has 9 more stickers than Sean. They have a total of 138 stickers.
- How many stickers does Glen have?
- How many stickers does Sean have?
(a)
Number of stickers that Ken has = 1 u
Number of stickers that Sean has = 1 u - 9
Number of stickers that Glen has = 5 u
Total number of stickers
= 1 u + 1 u - 9 + 5 u
= 7 u - 9
7 u - 9 = 138
7 u = 138 + 9
7 u = 147
1 u = 147 ÷ 7 = 21
Number of stickers that Glen has
= 5 u
= 5 x 21
= 105
(b)
Number of stickers that Sean has
= 1 u - 9
= 21 - 9
= 12
Answer(s): (a) 105; (b) 12
