At school athletic events you can buy 3 drinks and 2 hot dogs for $4.80 or you can buy 1 drink and 1 hot dog for $2.00. How much
mariarad [96]
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:

3x+2y=4.80

1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:

x+y=2
x=2-y

Using this value of x in first equation, we get:


3(2-y)+2y=4.80 \\ 
6-3y+2y=4.80 \\ 
6-y=4.80 \\ 
y=6-4.80 \\ 
y= 1.20

Thus the cost of one hot dog is $1.20
