The table shows that price of J will be $12, the quantity demanded of A will be 700, and the marginal revenue of E is 7.
The price of J will be:
= Total revenue / Quantity demanded
= 14400/1200
= 12
The quantity demanded of A will be:
= Total revenue/Price
= 11900/17
= 700
The marginal revenue of E will be:
= (13500 - 12800)/(900 - 800)
= 700/100
= 7
The variable cost of B will be:
= 6140 - 500
= 5640
The total cost of C will be:
= 6135 + 500
