Question 5

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, for which value of t would

the annual consumption reach 300 billion?

If needed, round your answer to 2 digits after the

decimal point.
