I can't remember how to solve for three variables. Could someone help me out? Here's the puzzle.
If 2 apples plus 3 oranges plus 4 bananas cost $1.45
4 apples plus 2 oranges plus 3 bananas cost $1.30
3 apples plus 4 oranges plus 2 bananas cost $1.30
What does each piece of fruit cost?
So far the closest I've gotten is that an apple and a banana cost as much as 2 oranges.
