Correct answer: C
Explanation
Cost of Dylan room for 5 days is (400 x 5)= €2000
Lunch and refreshment for 43 people for 5 days = (43 x 5 x €28)
= €6020
Total cost=€8020
Using the Lennon room: Room cost for 5 days = €2100
Lunch and refreshment for 49 people for 5 days = €6860
Total cost = €8960
Therefore, these changes will cost 8960 - 8020
= €940
