Step-by-step explanation:
the error is when it was divided, one of the fractions should be reversed to be multiplied
<u> </u><u>4</u><u> </u><u> </u> ÷ <u> </u><u>1</u><u>3</u><u> </u>
7. 28
<u> </u><u>4</u><u> </u> × <u>2</u><u>8</u><u> </u> ,like this

91
= <u> </u><u>1</u><u>6</u><u> </u>

Answer:
The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.
Step-by-step explanation:
Given a function y, the average rate of change S of y=f(x) in an interval
will be given by the following equation:

In this problem, we have that:

Find the average rate of change in the balance over the interval t = 0 to t = 5.


Then

The average rate of change in the balance over the interval t = 0 to t = 5 is of $20.82 a year. This means that the balance increased by $20.82 a year over the interval t = 0 to t = 5.
