1 u + 6 |

| Value |
4 |
2 |
|
| Total value |
4 u |
2 u + 12 |
6 u + 12 |
Number of grizzly bears = 1 u
Number of flamingos = 1 u + 6
Number of grizzly bears' legs
= 4 x 1 u
= 4 u
Number of flamingos' legs
= 2(1 u + 6)
= 2 u + 12
Total number of legs
= 4 u + 2 u + 12
= 6 u + 12
6 u + 12 = 108
6 u = 108 - 12
6 u = 108 - 12
6 u = 96
1 u = 96 ÷ 6 = 16
Number of flamingos
= 1 u + 6
= 16 + 6
= 22
Answer(s): 22
