Fran will have a base amount of $800 saved at the end of the 20 weeks assuming she continues to get at least 15 hours and her expenses don't increase (40x20 =800). At a net pay rate of $15 per hour (225/15=15), she will need to work an additional two hours per week for a total of 17 hours to earn the $600 needed to meet her goal. [15x2= 30, 30x20=600]
Answer:
Ax + By = C
A, B and C can be any number--including negative numbers, zero and one! So examples of standard form can look like this:
3_x_ + 7_y_ = 10, where A = 3, B = 7 and C = 10.
Or they can look like this:
x + 5_y_ = 6. In this case, A = 1, B = 5 and C = 6.
Or this:
8_y_ = 9. In this case, A = 0, which is why x does not appear in the equation. B = 8 and C = 9, as you would expect.
And here's one more:
3_x_ − 5_y_ = 12. Here, A = 3, B = −5 and C = 12. Notice that in this case, B is negative five!
The standard form of a linear equation is Ax + By = C, where A, B and C can be any number.
