<h2>Answer with explanation:</h2>
Let x be the number of sodas and y be the number of hot dogs.
Given : The concession stand at an ice hockey rink had receipts of $6200 from selling a total of 2600 sodas and hot dogs.
If each soda sold for $2 and each hot dog sold for $3.
Then we have a system of two linear equations in two variables :_
Multiply 2 to the each side of equation (1), we get
Eliminate equation (3) from equation (2), we get
Substitute the value of y in (1), we get
Hence, 1600 sodas and 1000 hot dogs were sold.
