MARK SCHEME
Body:

Step 1: Start (1)

Step 2 : Print (how many items did you purchase?)
Step 3: Read num

Step 4: For I = 1 to num do appropriate use of iteration (1)
Step 4i:Print (Enter the name of device) use of Output statement (1)

Step4ii: Read name1 use of Input statement (1)

Step 4iv: Print(Enter the cost of, name1)
Step 4v: Read cost

Step 4vi: Print (Enter “Y” if item is taxable or “N” if it is non-
taxable)

Step 4vii: Read Response

Step 4viii: If (Response = “Y”)then
(use conditional branching - 1 for If-then and 2 for If-then-else)2mks

Set vat Vatpercent * cost

Else
Set vat 0

Endif
Step 4ix: set total_cost vat + price

(1 for assignment variable and 1 for correct variables)
Step 4x: Print ( The total cost for a , name1 , is, total_cost)
(Output results 1 mark for each output) 2 marks

Step 4xi: Endfor
Step 5: Stop Terminator (1)

Key 3 – Using WHILE Loop

Header: Techno_Store appropriate Heading (1)

Declaration: The purpose of this algorithm is to output the name and
total cost for a device. (1)

Constant

Vatpercent = 0.16 Use of constant (1)
Variables:

Name1, of string Use of datatypes - three or more (2)
Cost, total_cost, vat of real
