The graph below shows relative price changes for fresh fruits and vegetables, sugars and sweets, and carbonated drinks between 1978 and 2009.

The line graph provides information about changes in the

price

of three different food product groups in the USA from 1979 to 2009 and the

overall

trend in the

consumer

price

index

over these 30 years.

Overall

,

it is clear that

prices

increased for the three food product groups, despite fluctuations. At a glance, an increase in the

prices

consumer

price

index

rose steadily from around 60 in 1979 to over 200 in 2009.

prices

also
