This is easy. Make two equations, and represent the Sandwiches with s and the drink with d. you get:
2s+d=10
s+2d=8
After simplifying and taking away a variable, you figure out that each sandwich costs 4 dollars and each drink costs 2 dollars.
(Heres the step by step algebra)
2s +dy = 10
s + 2d = 8
2s + d = 10
2s + 4d = 16
3d = 6
d = 2
2s + d = 10
2s + 2 = 10
2s = 8
s = 4
So,
Sandwich = £4
Drink = £2
