Fred's age is 13 years
Let
Fred's age = x
Jack's age = 2x + 4
After 8 years:
- Fred's age = x + 8
- Jack's age = 2x + 4 + 8
= 2x + 12
Sum of their ages = Fred's age + Jack's age
59 = (x + 8) + (2x + 12)
59 = x + 8 + 2x + 12
59 = 3x + 20
59 - 20 = 3x
39 = 3x
x = 39/3
x = 13 years
Therefore, Fred's age = 13 years

Step-by-step explanation:
To solve the problem it is necessary to pose some equations, which are the following:
Debt DVD = New Balance - Old Balance
With this we will calculate the net value that only has to do with the debt of the DVD:
Debt DVD: 7.75 - 2.50 = 5.25
Now, the other equation is the value per day that generates a delay.
Debt DVD / # days
Replacing
5.25 / 5 = 1.05
Then the daily fine for a overdueDVD is $ 1.05
