Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:
1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:
Using this value of x in first equation, we get:
Thus the cost of one hot dog is $1.20
