The program approves the purchase of a sweater only if it is cheaper than $20.00.

Answer:

PRINT "How much is this sweater"
INPUT COST
'
IF COST < 20 THEN
  PRINT "Buy the Sweater"    ' true branch
END IF
'
PRINT "done"
END

Since only sweaters LESS THAN $20.00 could be purchased, the correct relational symbol is < .

Several Choices

Often there are several options that might be included in a purchase. Each one might be accepted or rejected. Say that you are in the market for a new car:

You have decided to buy a new sports car. The base price is $20,000. There are two options:

The price of the car will be the base price plus the price of the options you have picked. Write a program that calculates the final price of the car.

Here is a incomplete version:

LET PRICE = 20000
'
PRINT "Type 1 if you want pin stripes, 0 if not"
INPUT STRIPES
'
IF ____________ THEN
  LET PRICE = PRICE + 250
END IF
'
PRINT "Type 1 if you want anti-lock brakes, 0 if not"
INPUT BRAKES
'
IF ____________ THEN
  LET PRICE = PRICE + 800
END IF
'
PRINT "Final price:", PRICE
END
