57 of his stickers while Oscar gave away
35 of his stickers. Given that Cody gave away 12 stickers more than Oscar, how many stickers did Cody have at first?

Cody's stickers |
Oscar's stickers |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
- 5x5 =
- 25 u |
- 3x7 =
- 21 u |
| After |
2x5 =
10 u |
2x7 =
14 u |
The number of cards that Cody and Oscar each had at first is the same. Make the number of cards that Cody and Oscar each had at first the same. LCM of 7 and 5 is 35.
Number of stickers that Cody gave away more than Oscar
= 25 u - 21 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of stickers that Cody had at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
