The temperature of magnesium must be at least \( 650 \) degrees for the metal to melt. A sample of magnesium is currently \( 255 \) degrees. The temperature of the magnesium is increased by \( 10 \) degrees every minute. Which inequality shows the number of minutes \( ( m ) \) needed to raise the temperature to the melting point? 

\( m > 39.5 \) 

\( m \geq 39.5 \) 

\( m > 87.5 \) 

\( m \geq 87.5\)
