Respuesta :
A is INCORRECT because Lucita's estimate is about right and if the decimal point was to the left of 2, then the answer would be -0.26 which is still too small.
B is CORRECT because again Lucita's estimate is about right and if the decimal is to the left of six the number would be -2.6 which is close to her estimate (-3)
C is INCORRECT because it is saying that -0.026 is the correct answer and Lucita's estimate was just too small which is incorrect since we know -0.026 is actually what is too small.
D is INCORRECT because it is saying that -0.026 is correct and if her estimate (-3) was too high, it would be bigger than the number she got which was -0.026 and regardless of anything we know -3 is not bigger that -0.026.
