How many chose apple juice and how many chose orange juice
:
I don't know how many pence in a pound, but here are the equations:

x = no. of apple juice drinks
y = no. of orange juice drinks
:
Total no. of drinks equation
x + y = 18
y = (18-x); you can use this for substitution in the total cost equation
:
Total cost equation:
22x + 24y = 4.08
