Eliza started her savings account with $100. each month she deposits $25 into her account. determine the average rate of change in eliza's account from the second month to the 10th month.

We start off with 100 dollars. Which in this case Eliza deposits 25 every month.

What is average rate of change?

It is a measure of how much the function changed per unit, on average, over that interval

So this meaning that

25x + 100 would be are main focus here.

Replace x with 2 since we are finding the change of the 2nd account

25(2) + 100 = 150

Do the same problem but replace x with 10

25(10) + 100 = 350 dollars

So the average rate of change would be 25 dollars
