Caden bought 34 more stickers than Valen and Valen bought 12 stickers more than Cindy. The total number of stickers Caden and Valen bought was 4 times the number of stickers Cindy bought.
- How many stickers does Caden need to give Valen so that they have the same number of stickers?
- How many stickers did all three of them have altogether?
Caden |
Valen |
Cindy |
1 u + 12 + 34 |
1 u + 12 |
1 u |
4 u |
1 u |
(a)
Number of stickers that Caden needs to give Valen so that they have same number of stickers
= 34 ÷ 2
= 17
(b)
Total number of stickers that Caden and Valen had
= 1 u + 12 + 34 + 1 u + 12
= 1 u + 1 u + 12 + 34 + 12
= 2 u + 58
4 u = 2 u + 58
4 u - 2 u = 58
2 u = 58
1 u = 58 ÷ 2 = 29
Total number of stickers that all three of them had
= 4 u + 1 u
= 5 u
= 5 x 29
= 145
Answer(s): (a) 17; (b) 145
