Write a solve each systen using substitution You want to make your grandmother's recipe for fudge. You have all the ingredients except sugar and chocolate. You have $10.50 to spend on the sugar and chocolate. Sugar costs $1.40 per pound, and chocolate costs $8.40 per pound. Your grandmother's recipe calls for 4 times as much sugar as chocolate. How much sugar and chocolate can you buy?

answer:

Grease an 8x8 inch square baking pan. Set aside.

Combine sugar, cocoa and milk in a medium saucepan. Stir to blend, then bring to a boil, stirring constantly. Reduce heat and simmer. Do not stir again.

Place candy thermometer in pan and cook until temperature reaches 238 degrees F(114 degrees C). If you are not using a thermometer, then cook until a drop of this mixture in a cup of cold water forms a soft ball. Feel the ball with your fingers to make sure it is the right consistency. It should flatten when pressed between your fingers.

Remove from heat. Add butter or margarine and vanilla extract. Beat with a wooden spoon until the fudge loses its sheen. Do not under beat.

Pour into prepared pan and let cool. Cut into about 60 squares.
