matrix: A bagel store orders cream cheese from three suppliers...

[Tami]

A bagel store orders cream cheese from three suppliers, Cheesy Cream Corp. (CCC), Super Smooth & Sons (SSS), and Bagel's Best Friend Co. (BBF). One month, the total order of cheese came to 100 tons (they do a booming trade). The costs were $80, $50 and $65 per ton from the three suppliers respectively, with the total cost amounting to $6,710. Given that the store ordered the same amount from CCC and BBF, how many tons of cream cheese were ordered from each supplier?

can someone help me?

Since you know it is a matrix related problem - did you set up the matrix?

What is the significance of the red text? (You changed the color of the text for some reason. What was that reason?)

For the rest, use what you learned back in algebra:

You are asked for the tons ordered from each supplier. So for what should the variables stand?

They have given you a total, being the sum of the orders from the three suppliers. What equation did you create from this?

You are told that two of the orders are of the same size. What equation did you create from this?

You are given the per-ton costs for each supplier, and given a total cost. What equation did you create from this?

This gives you three linear equations in three variables, which is a linear system that you can solve. By what method have you chosen to solve this system?

Where are you stuck in the solution process?

Please be complete. Thank you!
