Excel Case: Poke Mart Shop Cart
Case: Poke Mart Shop Cart
In this case we help the Poke Mart merchant to create a shop cart overview with prices, discount and total price. You will practice the skills that you have learned in the earlier chapters.
Copy values or type the following data:
To solve the case we need to complete the following:
 Prices for items (
C2:C8
)  Sub total (
B10
)  Add discount (
B11
)  Total price (
B13
)
Are you ready?
Start by creating the first formula for Item price*Shop
cart. We want the price to change when we change items in the Shop cart. Use the fill function on the range D2:D8
afterwards to save time.
Step by step:
 Select
C2
, type (=
)  Select
B2
 Type (
*
)  Select
D2
 Hit enter
Test the formula by Typing D2(1)
:
Did you get C2(200)
? That matches the price for one Pokeball!
Good job!
We need the same formula for C2:C8
, let's fill it downwards!
Note: We need relative references as we want the fill function to continue the formula to the next rows.
Fill D2:D8
to double check the prices:
That looks right!
Let us find the subtotal by using the SUM
function on the C2:C8
range.
 Type
B10(=SUM)
 Double click the
SUM
function  Mark the range
C2:C8
 Hit enter
Well done! You have successfully calculated the subtotal using the SUM
function.
Next, let's add a 10%
discount. Type F11(10)
:
Apply the discount to the subtotal:
 Select
B11
, type (=
)  Type
(F11/100)*B10
 Hit enter
Note: The (F11/100)
was used to change the value 10
to 0.1
, which is 10%
.
Subtract the discount B11
from the subtotal B10
to calculate the total.
 Select B13 type (
=
)  Select the minuend
B10
 Type (

)  Select the subtrahend
B11
 Hit enter
That is great!
You have completed all the tasks for the Poke Mart merchant.

Prices for items
RangeC2:D8
calculates the prices by multiplying item price and shop cart 
Sub total
TheSUM
function adds the rangeC2:C8

Add discount
The discount is calculated by usingF11(10)
into the formula inB11
