Auniversity begins year 1 with 80 faculty. they hire 4 faculty each year. during each year 10% (rounded to the nearest integer) of the faculty present at the beginning of the year leave the university. for example, in a year where there are 73 faculty at the beginning of the year, 7 would leave the university at the end of the year. the university wants to know how many faculty they will have at the end of year 10. the resulting spreadsheet can be found below. the formula copied down from e10 to e11: e18

At the end of year 10 will be 54 faculty.

credit history is used by lenders to determine whether you are a 'risky' person to give their money to.

having a short history provide very little data for the lenders. they wouldn't be able to determine your credit behavior from such a small samples. even if they are perfect.

having long credit history with few blemishes provide larger and more accurate data for the lenders to predict your credit behavior.
