Perry and Julian had the same number of stickers. Perry gave away
34 of his stickers while Julian gave away
35 of his stickers. Given that Perry gave away 12 stickers more than Julian, how many stickers did Perry have at first?

Perry's stickers |
Julian's stickers |
| Before |
4x5 =
20 u |
5x4 =
20 u |
| Change |
- 3x5 =
- 15 u |
- 3x4 =
- 12 u |
| After |
1x5 =
5 u |
2x4 =
8 u |
The number of cards that Perry and Julian each had at first is the same. Make the number of cards that Perry and Julian each had at first the same. LCM of 4 and 5 is 20.
Number of stickers that Perry gave away more than Julian
= 15 u - 12 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of stickers that Perry had at first
= 20 u
= 20 x 4
= 80
Answer(s): 80
