A car hire company makes the following charges:
•A one-off charge of £20:
•A charge of £25 for each day that the car is hired.
•A charge of 10p for each mile that car is driven.
Write down a formula that gives the total cost (£C) of hiring a car for D days and driving M miles. Use your formula to find the cost of hiring a car for 3 day and driving 200 miles.
how do i work this out ?
I would say
Cost = 20 + 25D + .1M
so if D=3 and M=200
Cost =20+25(3)+.1(200)
=....
Cost = 20 + 25(3) + 0.1(200)
= 20 + 75 + 20
= 115
To work this out, you can follow the formula given: Cost = 20 + 25D + 0.1M
Substitute D = 3 and M = 200 to calculate the total cost.
Cost = 20 + 25(3) + 0.1(200)
= 20 + 75 + 20
= 115
So, the cost of hiring a car for 3 days and driving 200 miles is £115.
