Instructions:
·
Filling
in all the student information data above correctly is worth 2 points.
·
Put
away all books, papers, and calculators.
·
Turn
off all beepers and cell phones.
·
Read
each question carefully and fill in the answer in the space provided.
Answers must be legible or they will be marked incorrect. If there are
multiple answers to choose from, please CIRCLE the correct answer. The question
will not be graded at all if there are multiple answers to choose from.
·
When
time has run out you will be told to put all pens/pencils down.
·
Be
sure to use values as determined by previous problems and do not use values
from problems that have not yet been solved per the ordering of the questions.
·
Use
cell references whenever possible.
·
Don’t
use a $ if NOT copying
·
Only
use the functions given.
·
Your
answer should update correctly when additional input data is added to the
problem or when input data is changed.
·
All
answers given should be “updatable” unless otherwise noted.
·
Do
not use extra IF structures. An example
of using an extra IF structure is IF(cond,true,false) when just the condition
would be the correct answer.
·
Only
use quotes when necessary – do NOT use quotes around Boolean values.
·
Always
use a reference functions versus a nested IF when 3 or more nested IFs might be
used and a reference function will work using the given data.
The
Worksheets:
SNEAKER –
has input data in columns A thru E.
FINANCE –
the years and annual interest rates are given in cells A3:A7 and B2:D2
respectively.
DISCOUNT
– includes discount amounts based on the type of shoe.
WEAROUT –
gives a level (A-E) based on the amount of miles it takes before a shoe will
wear out and buying a new pair of shoes will be necessary. Wear level A wears
out in less than 100 miles; wear level B lasts at least 100 miles but will wear
out before 250 miles; wear level C lasts at least 250 miles but will wear out
before 400 miles; wear level D lasts at least 400 miles but will wear out
before 500 miles; and wear level E lasts at least 500 miles.
1. (9 pts) Write an Excel
formula in cell sneaker!F3, which can be copied down to sneaker!F15, to
determine the discount price for the nw1 nike shoe. The discount amounts are given
on the discount worksheet based on the shoe type. NOTE: this formula should
return the discount price for the shoe (answer in sneaker!f3 is $120), not just
the discount amount (which for nw1 shoe is $30) or the discount percent (which
is 20% for a walking shoe).
=(1-VLOOKUP(C3,discount!A$2:B$6,2,FALSE))*E3
=E3-VLOOKUP(C3,discount!A$2:B$6,2,FALSE)*E3
Optional $ on column
2.
(7 pts) Write an Excel formula in cell sneaker!G3, which can be copied down to
sneaker!G15, to determine the wear level for the nw1 nike shoe. The wear level
is based on the miles to wear out found in D3 for the nw1 nike shoe. See the
description above for more information about the information on the wearout
worksheet.
=HLOOKUP(D3,wearout!B$1:F$2,2,TRUE)
Optional $ on column
Can default the 4th argument TRUE
3.
(7 pts) Write an Excel formula in cell wearout!B3, which can be copied across
to wearout!F3, to determine the percent of shoes with wear level A on the list
in the sneaker worksheet (i.e. as solved for above).
=COUNTIF(sneaker!$G3:$G15,B2)/COUNT(sneaker!$D3:$D15)
Optional $ on row
Can use any numeric column for the COUNT function (i.e. columns D, E
or F)
4.
(9 pts) Write an Excel formula in cell wearout!G3 to determine the wearout
rating for the Excel Sneaker Shop based on the following:
·
The
wearout rating is “excellent” if the % wear level for D and E together is at
least 30%
·
The
wearout rating is “good” if the % wear level for C is greater than the % wear
level for B
·
Otherwise,
the wearout rating is “other”.
=IF(E3+F3>=30%,"excellent",IF(D3>C3,"good","other"))
Okay if used AND(E3>=30%,F3>=30%) for excellent option
Lots of options for ordering the 3 possible results
No $ allowed
5. (7 pts) The owner of the Excel Sneaker Shop
mentioned that it took $150,000 to start up his company. You are interested in
doing the same, but want to determine what the monthly payment will be based on
several options from 1 to 5 years (see cells finance!A3:A7) and different
interest rates (see cells finance!B2:D2). Write an Excel formula in cell finance!B3,
which can be copied down and across to cell finance!D7, to determine the
monthly payment for a one year loan (see cell finance!A3) at an annual interest
rate of 10% (see cell finance!B2) compounded monthly.
=PMT(B$2/12,$A3*12,150000)
No extra $ allowed
6.
(9 Pts) Write an Excel formula in cell finance!B10, which can be copied down
and across to cell finance!D14, to determine how long it will take in years to obtain enough money
to start your own sneaker shop (i.e. for you to accumulate $150,000) if you invest the monthly payment given in cell
finance!B3 at an annual percentage rate of 15% (see cell finance!A9) compounded quarterly.
=NPER($A$9/4,B3*3,0,150000)/4
No extra $ allowed
Okay if leave out the zero argument but must have two commas present
SCORE __________/50
