Question: Next week you have to travel around parts of the country on business and have decided to hire a car from a car-hire company. You have contacted two companies which offer different services. The first company will rent you a car for £45 per day. The second company will charge you £30 per day but with an additional charge of 5p per mile travelled. You know you will require the car for four days but are unsure of the mileage you will cover.
