Putting It Together
After taking this module, you realize that you can create a system of linear equations based on the table you were given:Quantity for x | Quantity for y | Quantity for z | Total on bill before taxes | |
Invoice 1 | 1 | 5 | 6 | 1400 |
Invoice 2 | 2 | 4 | 8 | 1400 |
Invoice 3 | 4 | 3 | 12 | 1600 |
x + 5y + 6z = 1400
2x + 4y + 8z = 1400
4x + 3y + 12z = 1600
We should now be prepared to put this into a spreadsheet and have the technology do the calculations for us once we set up our equations:x | y | z | |||||||
1 | 5 | 6 | x | = | 1400 | x | 100 | ||
2 | 4 | 8 | y | = | 1400 | y | 200 | ||
4 | 3 | 12 | z | = | 1600 | z | 50 |
