LESSON 8 - DOUGHNUT DREAMING
ACTIVITY 8.1
MY DEMAND SCHEDULE FOR DAYDREAM DOUGHNUTS
Directions: Pretend you receive a weekly $10 allowance. Although you might
want to spend all $10 on doughnuts, remember that your $10 allowance must
pay for all of your expenses during the week, such as soft drinks, ice cream,
books, toys, movies, video games and donations. Record the number of doughnuts you would be willing and able to buy at each price during one week, using
one week’s allowance. Remember, if you are willing and able to buy a number of
doughnuts at a certain price, you should be willing and able to buy at least this
same number of doughnuts — and probably more — at any lower price.
