Graph exercise: after-school eats add to teenagers' weighty problems.

America's school lunches often present students with a tray full of calories, but school lunches are only part of the problem.

Another source of fat, calories, cholesterol, sodium, carbohydrates, and sugars comes from the thousands of fast-food bistros scattered across the map like so many pebbles on a beach. This graph shows two things--the recommended daffy caloric intake for male and female teenagers--and the calories provided in each serving of popular food items from fast-food chains around the U.S. Use the data to answer the questions below.

   (c) 500

   (d) 620

   (a) 2,040

   (b) 1,300

   (c) 3,100

   (d) 4,000
