Question 963120: I have the math problem listed below and was wondering if there is a formula that can be used to solve this. If there is a formula, could you show how to solve it and include each step? Thanks so much.
A box containing 3 oranges, 2 apples, and one banana weighs 15 units. Another box containing 5 oranges, 7 apples, and 2 bananas weighs 44 units. A third box containing 1 orange, 3 apples, and 5 bananas weighs 26 units. How much does each fruit weigh?

You can put this solution on YOUR website! n,p,b, the units per piece for OraNge, aPple, Banana.
Write equations in these variables to account for the three different costs.
That is the system to solve. Choose the method you want, matrix row operations, elimination, or substitution. My suggestion is use the "26" equation to elimininate terms of n from the "15" equation and the "44" equation. ... Go from there.
