Solving Systems with Gaussian Elimination · Exercise 59
Set up the augmented matrix that describes the situation, and solve for the desired solution.
A major appliance store has agreed to order vacuums from a startup founded by college engineering students. The store would be able to purchase the vacuums for $86 each, with a delivery fee of $9,200, regardless of how many vacuums are sold. If the store needs to start seeing a profit after 230 units are sold, how much should they charge for the vacuums?
