Answer:
a.
Average cost per meal = Variable cost per meal + Fixed cost allocated to one meal sold = $4 + Total fixed cost/ Number of meals sold per day = $4 + 1,200/750 = $5.60.
b.
Price per one meal as per the leader of the Scout = 150/30 = $5
As the selling price is $0.60 lower than the average cost per meal ($5-$5.60), the owner has come up with the loss of $0.60 per meal served under the Scout leader's suggestion.
However, his calculation is not reasonable, because among the $5.60 cost per meal, there is a factor of allocated fixed cost equals to $1.6 per meal which will incurred regardless of the suggestion being accepted or not.
Given his restaurant does not run at full capacity, his profit per one meal from accepting the offer should be calculated as Price per one meal as per Scout leader offer - Variable cost per one meal = $5 - $4 = $1.
