Answer:
The system of equations is
Step-by-step explanation:
Let
x ----> the number of minutes of calling time
y ----> the monthly cost of the calling plan
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
In this problem
Plan A

substitute
----> equation A
Plan B

substitute
----> equation B
therefore
The system of equations is
If you would like to know how much do you save per month, you can calculate this using the following steps:
your expenses: 36% of 2,847.69 = 36% * 2,847.69 = 36/100 * 2,847.69 = 1,025.17
2,847.69 - 1,025.17 = 1,822.52
saving 40% of your discretionary money: 40% of 1,822.52 = 40% * 1,822.52 = 40/100 * 1,822.52 = 729.008 = 729.01
The correct result would be: You can save 729.01 per month.
