Initial amount = 5000
Interest rate = 1.15
The amount increases exponentially.
Then we get the following equation
5000 \times 1.15 {}^{t}
In this formula t represents time.

The equation of doubling time
5000 \times 1.15 {}^{t}  = 10000
1.15 {}^{t}  = 2

First box -plot

Step-by-step explanation:

The given data set : 28\ 30\ 22\ 20\ 24\ 23\ 32

Arrange in order

20\ 22\ 23\ 24\ 28\ 30\ 32

We can see that the smallest data value = 20 and the largest date value = 32

Median = Middle most number = 24

in a box plot , both the whisker ends represents the minimum and the maximum data value. The median value is shown by the vertical line in the box.

In the given picture only first and fourth box plot showing the correct smallest and largest value to the given data set.

But the median value is correctly represented by the first one as the fourth one has median of 25.

Hence, the correct box plot for the given data : First
