She adds 20 USD each month to her account, starting with 145 USD. Therefore, the function that best models the total amount of She is a linear function that can be written like f (p) = 20p + 145. Where p is the number of months. (p > 0). For the first month f (1) = 20 (1) + 145 = 165 USD. For the second month f (2) = 20 (2) + 145 = 185 USD ...
