Question

Eliza started her savings account with $100. Each month she deposits $25 into her account. Write the function that describes the relationship between the amount Eliza deposits and the total amount in her account. Then, determine the average rate of change in the account from the 2nd month to the 10th month

Answer 1

Well she first put in 100.
Then in the first month she puts in 25.
The second month she has the 100 and the 25 and adds 25 more.

Can you write an equation for this?

Answer 2

100+(25)=400

Answer 3

Where did you get the 400 from?

Answer 4

i meant to putm100+(25)

Answer 5

That's only the first week. That's not an equation for what happens in general.
It's 100 + 25 per week. You aren't representing the "per week" part.
