AVERAGE(number1,number2,…)
COUNT(number1,number2,…)
LARGE(array,k)
MAX(number1,number2,…)
MIN(number1,number2,…)
RANK( number, ref, order)
ROUND(number, num_digits)
SMALL(array,k)
SUM(number1,number2,…)
1. (6 pts) Evaluate the following functions in two ways. The first way is to evaluate exactly as you see the data
in the worksheet given above. The second way is to delete all the zeroes in the range E4:E11; that is, instead of
the zeroes in E4:E11, there is a blank value instead.
as shown above
if blanks instead of zeroes
=COUNT(E4:E11)
_____8_____
____2______
=AVERAGE(E4:E11)
_____0.25__

=MIN(E4:E11)
_____0_____

2. ( 7 pts) Write an Excel formula in cell D12, which can be copied across to cell F12, to determine the
percent of people who ordered a “sugar” cone type. NOTE: Remember that the wording of this problem refers to
the determining of the percent of people who ordered “waffle” then “bowl” cone types as the equation you give
as a solution is copied across.
=SUM(D4:D11)/COUNT(D4:D11)
Okay if used columns C, E or F on the count function; $ okay on the column as well
=SUM(D4:D11)/SUM($D4:$F11)
=AVERAGE(D4:D11)
Accepted countif(d4:d11,1) or criteria variation of “1”, “=1”, “>0”, “<>0”
Optional $ on row
b. (5 pts) Write an Excel formula in cell D13 (not shown), which can be copied across to cell F13, to round
the percent given in the above problem to the nearest tenth of a percent.
=ROUND(D12,3)
Optional $ on row
3. (5 pts) If I enter the formula =D12+E12+F12, Excel returns 100%, however, if I add up the values as shown
in the worksheet by hand, the values add up to 101%. Explain how the 100% value was obtained and how the
101% value was obtained.
101% because that’s what the FORMATTED/DISPLAYED values add up to but
100% because that’s the correct PRECISE/ACTUAL value
4. (7 pts) Write an Excel formula in cell G4, which can be copied down and across to cell J11, to determine the
cost ice cream scoops specified for the raspberry chip order. NOTE: Remember that the wording of this problem
refers to determining the cost of scoops for each flavor as well as the cost of each cone type using the equation
you give as a solution since this is a copy down and across problem.
=C4*C$2

No extra $ signs allowed
5. (5 pts) Write an Excel formula in cell K4, which can be copied down to cell K11, to determine the total cost
of the raspberry chip order i.e. scoop cost plus cone cost. NOTE: Be sure to give an answer that will
automatically update should further costs to be added to the order. For instance, if I add another type of cone
between columns G and H, a flavored topping, or whipped cream, your solution should still work.
=SUM(G4:J4)
Optional $ on column
6. (4 pts) I put the formula =RANK(K4,K$4:K$11,1) in cell L4. Determine the results of this formula
assuming it’s copied down to cell L11.
