Seth bought 32 more stickers than Charlie and Charlie bought 19 stickers more than Yen. The total number of stickers Seth and Charlie bought was 4 times the number of stickers Yen bought.
- How many stickers does Seth need to give Charlie so that they have the same number of stickers?
- How many stickers did all three of them have altogether?
Seth |
Charlie |
Yen |
1 u + 19 + 32 |
1 u + 19 |
1 u |
4 u |
1 u |
(a)
Number of stickers that Seth needs to give Charlie so that they have same number of stickers
= 32 ÷ 2
= 16
(b)
Total number of stickers that Seth and Charlie had
= 1 u + 19 + 32 + 1 u + 19
= 1 u + 1 u + 19 + 32 + 19
= 2 u + 70
4 u = 2 u + 70
4 u - 2 u = 70
2 u = 70
1 u = 70 ÷ 2 = 35
Total number of stickers that all three of them had
= 4 u + 1 u
= 5 u
= 5 x 35
= 175
Answer(s): (a) 16; (b) 175
