Answer = 12
Explanation:
Let x be Timothy’s present age.
The, Adele’s present age = x+5
After 3 years, Timothy’s age = x+3
Adele’s age = x+5+3 = x+8
According to the question, we have
x + 3 = 2/3 (x+8)
3(x + 3) = 2x + 16
3x + 9 = 2x + 16
3x - 2x = 19 - 9
x = 7
Therefore, Timothy’s current age is 7 years and Adele’s current age is 12 years
Price should be greater than 730.
