Final answer:
To model the bank account situation, use the linear model b = -50m + 2500.
Step-by-step explanation:
To model this situation, we need to determine the relationship between the balance in the bank account and the number of months. Let's use 'b' to represent the balance and 'm' to represent the number of months. Initially, the balance is $2500, and every month $50 is withdrawn. This means that for each month, the balance decreases by $50. So we can express the linear model in slope-intercept form as:
b = -50m + 2500
