Carl had 5 times as many pink markers as brown markers. After giving away 8 pink markers and buying another 40 brown markers, he had an equal number of pink and brown markers. How many pink markers did Carl have at first?

Pink markers |
Brown markers |
| Before |
5 u |
1 u |
| Change |
- 8 |
+ 40 |
| After |
5 u - 8 |
1 u + 40 |
The number of pink and brown markers is the same in the end.
5 u - 8 = 1 u + 40
5 u - 1 u = 40 + 8
4 u = 8 + 40
4 u = 48
1 u = 48 ÷ 4 = 12
Number of pink markers that Carl had at first
= 5 u
= 5 x 12
= 60
Answer(s): 60
