Hello, thank you for taking the time to post your question!
Did it give you any additional information beyond that? You could use what’s given to set up one equation
4apples + 3bananas = $6.75
But we would need to know something about how the prices between them are related to one another in order to solve for the exact value of each
I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
