Discount Sweater

Here is a new story problem:

You could not buy the sweater you wanted (the one with the reindeer and snowflakes on it) and now need to find a cheaper sweater. Write a program that approves a purchase only if it is for less than $20.00.

Here is the program:

PRINT "How much is this sweater"
INPUT COST
'
IF ____________ THEN
  PRINT "Buy the Sweater"    ' true branch
END IF
'
PRINT "done"
END
