1.05

Step-by-step explanation:

Given: Yui makes a list of the balances in her savings account at the end of each month. She notices that each month’s total is 5% greater than the previous month’s total.

Let the first term be =x.

Then the second term will be :-

Now, the common ratio will be given by :-

Therefore, the common ratio for the given problem will be :-

step-by-step explanation:

what is the figure? attach a picture.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
