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.
DochEvi [55]

Answer:

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.
