Use the line graph to answer the exercise.

  

Concept used:

• A line graph—also known as a line plot or a line chart—is a graph that uses lines to connect individual data points.
• A line graph displays quantitative values over a specified time interval.

Calculation:

The given line graph is −

  

From the given line graph −

The point on the graph to the right shows 8 dinners at 10 P.M.

The point on the graph to the right shows 22 dinners at 6 P.M.

No. of fewer dinners Ferraro’s were at 10 P.M. than 6 P.M. = 22 − 8 =14 dinners.
