| Total value |
4 u |
2 u + 12 |
6 u + 12 |
Number of polar bears = 1 u
Number of eagles = 1 u + 6
Number of polar bears' legs
= 4 x 1 u
= 4 u
Number of eagles' legs
= 2(1 u + 6)
= 2 u + 12
Total number of legs
= 4 u + 2 u + 12
= 6 u + 12
6 u + 12 = 114
6 u = 114 - 12
6 u = 114 - 12
6 u = 102
1 u = 102 ÷ 6 = 17
Number of eagles
= 1 u + 6
= 17 + 6
= 23
Answer(s): 23
