Answer:
Dropping Freeflight's routes between Europe and United States would reduce the overall profits of Freeflight Airlines by $304,000 monthly($880000-$576000)
Explanation:
As a result of dropping routes between Europe and United States,total revenue drops to $6.22m and variable costs to $2.22m,but only 20% of fixed costs can be saved ,hence current fixed costs become $3.42m giving overall profit of $0.58m instead of $0.88m recorded previously when all routes were operational.
