Answer:
$1.35
Step-by-step explanation:
Set up a system of equations, where d represents the price of one drink and s represents the price of one sandwich:
3d + 5s = 25.05
4d + 2s = 13.80
We can solve this by elimination by multiplying the top equation by -2 and multiplying the bottom equation by 5.
-6d - 10s = -50.1
20d + 10s = 69
Add them together:
14d = 18.9
d = 1.35
