Answer:

Step-by-step explanation:
Let's call B the balance of Jacob's checking account. Each week he withdraws $40 from his actual balance of $1000, so if x is the number of weeks, the account's balance is
B=1000-40x
The balance must be more than $400, which means

That is the inequality to model the situation. If we wanted to know the limit for x, we can solve the inequality. Operating:

600>40X

Or x<15
Which means Jacob can withdraw $40 14 times at most to maintain the minimum balance requirement
