The first paragraph on page 211 should read as follows:
If the speed property of an object is equal to 2GHz, add 200 to the value of the_price;
otherwise, add 100 to the_price. If the hdspace property of an object is 80GB, add 50 to the
value of the_price; otherwise, add 25 to the_price. If the ram property of an object is 1GB,
add 150 to the value of the_price; otherwise add 75 to the_price. End the function with
a return statement that returns the value of the variable the_price.
