Step-by-step explanation:
Let the Price of each Hot dog be x.
Also Let the price of each Soda be y.
Now Given:
John bought 6 hot dogs and 4 Soda and paid $6.70.
Now Total Money paid by John is equal to Sum of Number of hot dogs he bought multiplied by Cost of each hot dogs and Number of Soda he bought multiplied by cost of each soda.
Framing in equation form we get;
Dividing by 2 on both sides we get;
Also Given:
Jessica bought 4 hot dogs and 3 Soda and paid $4.65.

Multiplying equation 1 by 3 we get;
Also Multiplying equation 2 by 3 we get;
Now Subtracting equation 4 from equation 3 we get;
Now Substituting the value of x in equation 1 we get;
Hence Hot dog cost for $0.75 and Soda cost for $0.55.
