Answer 1

Well you are reading one customer record and then you stop!

You have the statement
perform discount()
but I don't see a discount routine. Unless the second perform discount() is supposed to be the routine. It has no indication of starting a routine and no indication of ending a routine. You have the full English language available to you when you write pseudo code. Don't waste any of it by trying to cut corners.

Process_Customers
open customer file
read customerRecord
do until EOF customerFile
do discount()
do calculation()
read customerRecord
enddo /*customerFile */
exit

discount()
discount=0
if quantityOrdered > 100 then
discount = .20
else
if quantityOrdered > 12 then
discount = .10
endif
endif
return

I will let you do the rest.
