Question

Jessica has $30 in her bank. Every month she adds $5 to save. What is the recursive formula for the amount of money in her bank after n months?

A) M(n) = 30 + 5n
B) M(n) = 5n
C) M(n) = 30n
D) M(n) = 35n

Answer 1

The recursive formula for the amount of money in Jessica's bank after n months is M(n) = M(n-1) + 5.

Step-by-step explanation:

The recursive formula for the amount of money in Jessica's bank after n months is M(n) = M(n-1) + 5, where M(n-1) represents the amount of money in her bank after n-1 months.

To calculate the amount of money in her bank after a certain number of months, we need to start with the initial amount of $30 and then add $5 for every subsequent month. For example, after 1 month, Jessica will have $30 + $5 = $35 in her bank. After 2 months, she will have $35 + $5 = $40, and so on.
