Blue flags |
Total |
| Before |
4 u |
3 u + 55 |
167 |
| Change |
- 1 u |
- 55 |
|
| After |
3 u |
3 u |
|
Total number of flags at first
= 4 u + 3 u + 55
= 7 u + 55
7 u + 55 = 167
7 u = 167 - 55
7 u = 112
1 u = 112 ÷ 7 = 16
Number of purple flags that Ryan had at first
= 4 u
= 4 x 16
= 64
Answer(s): 64
