Explanation:
Note: The complete question is attached as picture below
We know that there is a total of 90 units of oil and 30 units is consumed in period 0.
So, in period 1, the consumption amount will be = 90-30=60 units.
So, Q1 = 192 - 8P
For 60 units, the price will be 60 = 192 - 8P
8P = 192 - 60
8P = 132
P = 132 / 8
P = 16.5
So, the price in period 1 is $16.50
