Respuesta :

We know that she found 100 fish at first. 100
Then she found 70 more, 32 of which have already been tagged. 70 - 32 =  38
100 + 38 = 138
138 should be the first estimate

A week later she catches 123 fish. 
74 of which had tags. 123 - 74 = 49
138 + 49 = 187
187 is your second estimate

C. It proves that there are more fish than originally thought and that the first estimate isn't as accurate

D. The 2nd estimate seems more accurate because the estimate is greater than the 1st estimate
