4. A university 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 was ___________.

Note: If the answer is a formula, there is no need to begin that answer with =. Please do not put any unnecessary spaces or () in your response.

Using the information in the spreadsheets below, what would be the row input cell for a two-way data table? Note: If the answer is a formula, there is no need to begin that answer with =. Please do not put any unnecessary spaces or () in your response.

27. In the spreadsheet shown below, we computed profit earned by selling houses by entering the formula =F8-E8 in cell G8 and copying it down to G9:G11. We used the word open to denote a house that is not yet sold. Unfortunately, when a house has not yet been sold our spreadsheet shows the #VALUE error, because you cannot subtract the buy price from the word open. We would like to "error trap" Column G so that when a house has been sold the correct profit has been computed and if the house has not yet been sold a _ will be entered in Column G. How many of the following formulas could be entered in cell G8 and copied down to G9:G11 to achieve this goal?

• I. IFERROR(F8-E8,"_ ") • II. ISERROR(F8-E8," _") • III. IF(COUNT(G8)>0,F8-E8,"_") • IV. IFERROR(F8-E8,_) • V. IFERROR(E8-F8,"_ ")
