How much money will you need in your wallet? To work it out, you've costed up your first day.
Entrance to water park £15 Taxi £10 Lunch and Evening meal £13 Bottle of wine £6 Pint of beer £1.25
You decide you need £45 a day.
How much cash will you need altogether? You can work this out by multiplying the daily amount - £45 - by the number of days you are away - 14. This makes the sum 45 x 14.
