Answer:
The new price of copper will be 3.48 dollar per metric ton
Missing inf:
the demand equation is Q = 27 −3P
the supply equation is Q = −9 + 9P
Explanation:
If demand increase by 35:
Qd = (27-3P) x 1.35
Qd = 36.45 - 4.05P
Now, we solve for the new equilibrium Price will ve:
36.45 - 4.05P = -9 + 9P
36.45 + 9 = 9P + 4.05P
45.45 = 13.05P
P = 3.48275862 = $3.48
