Answer: 1000 hot dogs and and 1600 sodas were sold.
Step-by-step explanation:
Let x be the number of hot dogs and y be the number of sodas.
Given : The concession stand at an ice hockey rink had receipts of $6200 from selling a total of 2600 sodas and hot dogs.
Each soda sold for $2 and each hot dog sold for $3 .
Then, we have the following system of two linear equations:-
[tex]x+y=2600-----------(1)\\\\3x+2y=6200-----------(2)[/tex]
Multiplying 2 on both sides of (1), we get
[tex]2x+2y=5200------------(3)[/tex]
Now, Eliminate equation (3) from equation (2), we get
[tex]x=1000[/tex]
Put x=1000 in (1), we get
[tex]1000+y=2600\\\\\Rightarrow\ y=2600-1000=1600[/tex]
Hence, 1000 hot dogs and and 1600 sodas were sold.
