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

Justin's stickers |
Tim'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 Justin and Tim each had at first is the same. Make the number of cards that Justin and Tim each had at first the same. LCM of 4 and 5 is 20.
Number of stickers that Justin gave away more than Tim
= 15 u - 12 u
= 3 u
3 u = 12
1 u = 12 ÷ 3 = 4
Number of stickers that Justin had at first
= 20 u
= 20 x 4
= 80
Answer(s): 80
