Answer:
3.5 weeks
Step-by-step explanation:
so you start out with 510
each day you subtract 20
day 1: 510 -20 = 490
day 2: 490 -20 = 470
day 3: 470 -20 = 450
day 4: 450 -20 = 430
and so fourth.
20 WEEKS is how long you can last.
First off, you need at least $100 in your account to avoid the fee and you currently have $510. With that being said, you're taking out $20 every week.
The first thing you can do would be to start at $410 (since that's $100 less than what you can use) and divide that by 20 (since that's what you're taking out every week) 410 / 20 = 20.5. That's 20 weeks because you have to round down to the nearest whole number.
Second What you can do to find how many weeks you can take this out by starting at $100 and adding $20 for every week. So 120, 140, 160, 180, 200, 220, 240, 260, 280, 300, 320, 340, 360, 380, 400, 420, 440, 460, 480, 500. This also gives you 20.
You can take $20 out of your account for 20 WEEKS until you have to pay the low-balance fee.
