Multiple Choice

Solve the problem.
-Approximately one-fourth of all glass bottles distributed will be recycled each year. A beverage company distributes 380,000 bottles. The number still in use after t years is given by the function $\mathrm { N } ( \mathrm { t } ) = 380,000 \left( \frac { 1 } { 4 } \right) ^ { \mathrm { t } }$ . After how many years will 3000 bottles still be in use? Round your answer to the nearest tenth.

A) $3.5 \mathrm { yr }$
