Two hot dogs and one soda cost 3 DOLLARS If two hot dogs and two sodas cost 4 DOLLARS 50 CENTS what is the cost of a hot dog?

Let 'H' represent the number of hot dog(s).

Let 'S' represent the number of soda(s).

2H+1S=3.00

2H+2S=4.50

Firstly, we know that soda's cost $1.50 each, because $4.50-$3.00 = $1.50.

Now take $3.00 - $1.50, and you are left with $1.50

Divide $1.50/2h = $0.75

Therefore, it is $0.75 per hot dog.
