Answer 1

Jason has put 110 in the bank to start with in February.

Explanation:

Given:

Amount in Account till December 31 = 325

Money added on birthday = 85

Each month money added = 13

Number of Months from March to December = 10

We need to find the Money he put in the bank in February.

Solution:

Let the Money he put in the bank in February be 'x'.

Now We know that Amount in bank till December is equal to Sum of Money he put in the bank in February and Money added on birthday and Money added each month multiplied by number of months.

framing in equation form we get;

`x+85+13*10=325\\\\x+85+130=325\\\\x+215 =325`

Now Subtracting both side by 215 using Subtraction property of equality we get;

`x+215-215 =325-215\\\\x=110`

Hence Jason has put 110 in the bank to start with in February.
