Virty [35]

Answer:

A

Step-by-step explanation:

First, find Neeta's total height in inches:

4 feet in inches is 4*12, which equals 48

Add the other 7 inches of her height to get 55 inches.

Then, subtract her initial height from her current height.

55 - 17 = 38. That is how many inches she has grown. Convert that to feet by dividing 38 by 12.

You get about 3.16, which is over 3 feet. So A is the correct answer.
