The Answer is SHAPE \* MERGEFORMAT
(a)

\begin{aligned}Q_{D} & =Q_{S} \600-10 \mathrm{P} & =900 \-10 \mathrm{P} & =300 \\mathrm{P} & =-30 \\mathrm{P} & =0\end{aligned}

\begin{aligned}Q_{D} & =600-10 \mathrm{P} \& =600-10(0) \& =600 \Q_{S} & =900\end{aligned}

\quad

600 pounds of newspaper is recycled and 300 pounds of newspaper ends up in landfills. One proposal to eliminate the alleged "glut" of used newspaper is to require newspaper publishers to purchase recycled newspaper and substitute it for Canadian newsprint (the paper that newspapers are printed on) in the printing process.
(b) Q_D = 1200 - 10P

ext { (c) } \begin{array}{rlrl}Q_{D} & =Q_{S} & Q_{S} & =1200-10(\mathrm{P}) \1200-10 \mathrm{P} & =900 & & =1200-10(30) \10 \mathrm{P} & =300 & & =900 \\mathrm{P} & =30 &\end{array}

900 pounds of used newspaper is recycled. No used newspaper ends up in landfills.
(d) Yes. The amount of used newspaper in landfills decreases from 300 pounds to 0 pounds.
(e) See the graph below. $SHAPE \* MERGEFORMAT (a) \begin{aligned} Q_{D} & =Q_{S} \ 600-10 \mathrm{P} & =900 \ -10 \mathrm{P} & =300 \ \mathrm{P} & =-30 \ \mathrm{P} & =0 \end{aligned} \begin{aligned} Q_{D} & =600-10 \mathrm{P} \ & =600-10(0) \ & =600 \ Q_{S} & =900 \end{aligned} \quad 600 pounds of newspaper is recycled and 300 pounds of newspaper ends up in landfills.
