Answer 1

Sophia is correct in calculating the expression, but it does not necessarily represent her uncle's age.

Sophia is: 31

Her uncle's actual age is: unknown

Answer 2

47?

Answer 3

If Sophia added 5 to her age (12) and multiplied the sum by 3, the result would be 51. Then, subtracting 4 from 51 gives 47. So if Sophia's Uncle Reynald's age is actually 47, then she would be correct. However, the problem only states that adding 5 to Sophia's age, multiplying by 3, and subtracting 4 would give Reynald's age, but it does not state that Reynald's age is actually 47. Therefore, we cannot assume that Sophia's calculation represents Reynald's actual age.
