Given:
The growth rates of both bank accounts are given as:
Now, as per question, we need to find the value of 'x' when the value of . Or,
Now, we can do this by checking the values of 'x' by hit and trial method.
Let . The inequality becomes:
Let . The inequality becomes:
Let . The inequality becomes:
Let . The inequality becomes:
Therefore, the value of 'x' for which is 4.
So, from the fourth month onwards, the balance in becomes greater than
.
The graphical solution is shown below to support the same.
From the graph, we can conclude that after the 'x' value equals 3.4, the graph of lies above of

Step-by-step explanation:
According to the information given in the exercise, you know that:
of the group's video games is at Jerome's house.
of the group's video games is at Mario's house.
Then, you need to add those fractions in order to solve the exercise.
Notice that the denominators of the fractions are different; so in this case, you need to multiply them in order to find the Least Common Denominator (LCD). This is:
Now, the procedure is:
1- Divide each original denominator by the LCD and multiply the numerators by the quotient obtained.
2- Add the products (This sum will be the numerator).
Then, you get the following result:
