Hope this helps :)
The intersection of the steps is just a fancy way of asking wi\hich numbers are in both equations so lets look and see :)
The 1st = 0...1...5...7...8
The 2nd =0........5...7........9
Answer = D {0, 5, 7}
Hope this helps have any questions let me know :)

Answer:
5040,56
Step-by-step explanation:
We have to construct pass words of 4 digits
a) None of the digits can be repeated
We have total digits as 0 to 9.
4 digits can be selected form these 10 in 10P4 ways (since order matters in numbers)
No of passwords = 10P4
= 
b) start with 5 and end in even digit
Here we restrain the choices by putting conditions
I digit is compulsorily 5 and hence only one way
Last digit can be any one of 0,2,4,6,8 hence 5 ways
Once first and last selected remaining 2 digits can be selected from remaining 8 digits in 8P2 ways (order counts here)
=56
Answer:
£b = £1.68
A = £44.68
Step-by-step explanation:
Given:
A = 5 + 1.9m + b
Where,
A = total cost
m = number of miles travelled
£b = charge for booking online
£5 = fixed charge
A. Harry
A = £29.48
m = 12 miles
£b = ?
A = 5 + 1.9m + b
29.48 = 5 + 1.9(12) + b
29.48 = 5 + 22.8 + b
29.48 = 27.8 + b
29.48 - 27.8 = b
b = 1.68
£b = £1.68
b) If Sue books online and travels 20 miles, what will be
A = 5 + 1.9m + b
= 5 + 1.9(20) + 1.68
= 5 + 38 + 1.68
= 44.68
A = £44.68
