Let's start off by working out the cost for one person. This person has to spend 130 pounds on travel and have 350 pounds of spending money. So far that is 130+350 = 480 pounds. Then it says the hotel costs 60 pounds per day. At 7 days, it will cost one person 7*60 = 420 pounds. This adds onto the 480 to get 420+480 = 900.
Therefore, each person will need 900 pounds to go on a 7 day trip. If we had 4 people going, then 4*900 = 3600 pounds is needed total.
Answer: £3600
