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 :_
[tex]x+y=2600--------(1)\\\\2x+3y=6200--------------(2)[/tex]
Multiply 2 to the each side of equation (1), we get
[tex]2x+2y=5200----------(3)[/tex]
Eliminate equation (3) from equation (2), we get
[tex]y=1000[/tex]
Substitute the value of y in (1), we get
[tex]x+1000=2600\\\\\Rightarrow\ x=1600[/tex]
Hence, 1600 sodas and 1000 hot dogs were sold.
