Answer:
Mike will rent the car for 6 days.
Explanation:
Let Mike rents a car for n days.
It is given in the question that for the first day rental of the car was £445.
So the days left in n days after first day rental = (n - 1)
For (n - 1) days rental will be = £60(n - 1)
Total rental including first day rental = £145 + £60(n - 1)
Now the equation representing the total fare will be
445 = 145 + 60(n - 1)
445 - 145 = 60(n - 1)
300 = 60(n - 1)
n - 1 =

n = 1 + 5
n = 6 days
Therefore, Mike will rent the car for 6 days.
