Based on the information given, it should be noted that the cost of the pretzel is $0.04.
Let the coke be represented by c.
Let the pretzel be represented by p.
Based on the information,
c = p + 2 ..... i
c + p = 2.08 ... ii
p + 2 + p = 2.08
2p + 2 = 2.08
2p = 2.08 - 2
2p = 0.08
p = 0.08/2 = 0.04
Therefore, c = 2 + 0.04 = 2.04
