Answer 2

Answer: It will take only 4 years to make the sum of their ages equal to 100.

Step-by-step explanation:

1. First, you have to add all the initial ages.

5 + 29 + 54 = 88

2. Since they're asking how many years the ages will become 100, you have to subtract 88 from 100.

100 - 88 = 12

3. Now, divide 12 by the number of people (3 people are there, Rachel, her mother, and her grandmother)

12 ÷ 3 = 4

Thus, the answer is 4.
