Between 2000 and 2010, the use of opioids was
exploding in the USA. We use MME (Morphine
Milligram Equivalents) as a measure of doses used.
It went from 91 billion doses in 2000 to a level 159%
higher in 2009.
Using the linear model to estimate consumptions,
what would be the equivalent annual growth rate
that occurred between 2007 and 2009?
Give your answer in % and if needed, round your
answer to 2 digits after the decimal point.
