Answer:
43
Step-by-step explanation:
Define x:
Let the number of donkeys be x.
Since there are 114 heads,
There must be (114 - x) ostriches.
Each donkey has 4 legs and each ostrich has 2 legs.
Given that total number of legs is 314.
4x + 2(114 - x) = 314
4x + 228 - 2x = 314
2x + 228 = 314
2x = 86
x = 43
Find the number of donkeys:
Number of donkeys = x = 43
