3 A wine producer has three wine varieties at various alcohol concentrations. varitey B has 20% alcohol and variety C has 12% alcohol. How many milliliters of each variety should she use to make 750 mL bottle of wine of 12% alcohol, if she must use 4 times as much of the variety A as the variety C? Set up a system of linear equations to determine how many millimeters of each variety were use. Let x be the number of millimeters of variety A, y be the number of millimeters of variety B and z be the number of millimeters of variety C. Make sure you justify your answer by showing all the steps. Sofre the system of linear equations you found in part (a) using Gaussian elimination on an augmented matrix. You need to use elementary row operations to reduce your augmented matrix into row-echelon form. Make sure you write down the elementary row operations that you use at each of the steps and give exact solution If you solve the system using other method, you will get 0.

varitey B has 20% alcohol and variety C has 12% alcohol. How many milliliters of each variety should
she use to make 750 mL bottle of wine of 12%% alcohol, if she must use 4 times as much of the variety A as
the variety C?
Set up a system of linear equations to determine how many millimeters of each variety were
use. Letx be the number of millimeters of variety A, y be the number of millimeters of variety B and
z be the number of millimeters of variety C. Mfake sure you justify your answer by showing all the
steps.
Solve the system of linear equations you found in part (a) using Gaussian elimination on an
augmented matrix. You need to use elementary row operations to reduce your augmented matrix into
row-echelon form. Make sure you write down the elementary row operations that you use at each of
the steps and give exact solution. If you solve the system using other method, you will get 0. Make

Ella has a cell phone plan. She tells you that after 8 months, she has paid a total of $760 and after 10 months, she has paid a total of $840. She does not remember the cost of the phone. Let's start by converting these to coordinates (m, C) where the inputs, m, are the number of months since Ella bought the phone, and the outputs, C, represent the total cost that Ella has paid after that many months. Coordinate for eight months: Coordinate for ten months:
