Answer:
We are charged 21 p/d +0.10 p/m so for every 5 mile it is 0.50 every 10 mile it is 1.00 and every 2 mile it is 0.2. LEts say it is 18 mile day 1 and 43 mile day 2.
Explanation:
Day 1
(21)+ (1 )+ (0.5) +(0.2)+(0.1)
= 21 + 1.8
Day 2
(21)+ (4) + (0.2) + (1)
=21 + 4.3
Total 2 days = 42 rental and 6.1 petrol
Full total rental and petrol = 42 + 6.10 = 48.10
