Answer: a. will cause him to raise his price and reduce the number of meals that he serves
Step-by-step explanation:
The owner makes a lot of meals that rely on salmon. With salmon prices going up, he will have to pay more money to buy the salmon that he uses to prepare the meals.
This would reduce his profit margin. He will therefore have to increase the price at which he sells his meals so as to recuperate the increased costs. He will also reduce the number of meals he serves because he will have to buy less salmon so that he does not incur a larger cost.
