ivia started her banking account with $100 and is increasing the account $20 per month Which type of function does this situation model

A positive function because the rate of her deposits of money is increasing because it adding $20 each month so her money is going up.

Step-by-step explanation: The independent variable is the variable that is being changed, in this case it is the amount of months(the IV is often times x). The amount of months that pass by determines how much money Olivia is earning.  Given that Olivia started her banking account with $100 and is increasing the account $20 per month.

Here the variable which changes independently is the independent variable

Hence no of weeks elapsed would be the independent variable

The dependent variable would be the variable which changes whenever number of weeks changes.

Here dependent variable is the total balance in the account in a particular week

D=100+20n where n= no of weeks that lapsed

and D= depositing in the bank

The independent variable is the amount of months.
