53% of Jame's monthly income is used as retirement fund. 18% of it is used as education fund and 9% of it is used as income tax. The remaining $2400 is used for daily expense. How much does James earn each month?

So the percentages add up to 80% of her paycheck. The remaining 20% is equal to $2400. $12000 is the amount she makes per month.

Step-by-step explanation:

Knowing that 20% = 2400, you can divide 2,400 by .2 (20 percent) to get the monthly amount of money. To fact check this, multiply 12,000 by .8, this is the amount she spent on her other expenses (retirement, education and income tax). If you add this total (9600) to 2400, you will get the answer, 12000 aka her monthly income.

Since it is hard to tell what the graph is by your description i will just put the definitions down and you see by yourself: a coincident system is two lines that are on the same slope and y- intercept (the same line). if you see only one line then it is coincident. if you don't it is not coincident.a inconsistent system is when the two lines are parallel. if they are parallel they are inconsistent because they will never meet.a consistent system is when two lines actually do meet. remember that the problem states which is the  best  describes the graph.an independent system system is when the two lines meet at least once.
