Write an algorithm to settle the following question: A bank account starts out with $10,000. Interest is compounded monthly at 6 percent per year (0.5 percent per month). Every month, $500 is withdrawn to meet college expenses. After how many years is the account depleted?

Here is what I got so far. Can you tell if I am on the right track.

Step 1 Start with the table:
Month Balance
0 $10,000.00

Step 2 Repeat steps 2a, 2b, 2c while the balance is greater than $0.00
Step 2a. Add a new row to the table.
Step 2b. In column 1 of the new row, labeled "Month", put one more than the preceding month value.
Step 2c. In column 2 of the new row, labeled "Balance", place the value of this formula
b * (1 + 0.005) - 500
where b is the preceding balance value.

Step 3 Read the last number in the month column (let's call it months). Report that the account will be depleted in (months / 12) years and (months % 12) months.

Which of the following methods could be considered a “best practice” in terms of informing respondents how their answers to an on-line survey about personal information will be protected? respondents are informed that investigators will try to keep their participation confidential; however, confidentiality cannot be assured. respondents are informed that a research assistant will transfer all the research data to a password-protected computer that is not connected to the internet, via a usb flashdrive. the computer is located in a research team member’s office. the investigator uses the informed consent process to explain her institution’s method for guaranteeing absolute confidentiality of research data. the investigator uses the informed consent process to explain how respondent data will be transmitted from the website to his encrypted database without ever recording respondents’ ip addresses, but explains that on the internet confidentiality cannot be absolutely guaranteed.

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
