Answer:
B. buyer must pay $2.33 per gallon for the rest of the year.
Step-by-step explanation:
The correct answer is B. The seller agrees to supply gasoline for next year at $3 per gallon, the buyer agreed to it. When the gasoline prices declined the buyer insisted to reduce price and seller agreed to it. When the prices rise again the seller asked to raise price but buyer refused. Buyer cannot terminate the contract instead it has to continue buying at $2.33 per gallon if the seller is agreed to sell on this price for the rest of the year.
