How I calculate the total price?
I'm assuming you do not understand the mileage rate. Take, for example Renault Megann. The figures are 21,20,125,2 This means that the minimum age of 21 Day Price £ 20 Weekly Rate £ 125 Miles Price 2 Mileage Rate 2 is 0.40, 0.30, 0.20 This means 0 to 1000 miles £ 0.40 (ie 40p) per kilometer from 1001 to 5000 miles 30 pence per mile more than 5001 miles at 20 pence per mile. So total price for the collection of cars (in this case Megann) for 1 week, 5 days, 4000 miles covered, assuming that they are in Week 25 1 £ 125 5 Days 5 * £ 20 = £ 100 4000 miles 1000 miles @ 40p = 400 pounds, 3000 miles @ 30P = £ 300 Insurance (under 25) 9 days @ £ 1.50 = £ 13.50 total so far 125 100 + 400 + 300 = 13.5 £ 938.50 Vat@17.5% = 0.175 * 938.5 = £ 164.24 = Total £ 1102.74 Rent (To expensive to treat Hertz) Hope this helps
