You are given an annual interest rate of 4.2% compounded monthly for 20 years, mortgage amount of $235,000. You are asked to find the monthly payment. You need the compound interest formula to solve this problem. The answer is $1,449.
For this case we must solve the following system of equations:

We multiply the first equation by -2:

We add the new equation with the second one:

We have different signs subtracted and the sign of the major is placed:

Now we find the value of the variable "y":

Thus, the solution of the system is given by:

Answer:

8: tenths
9:hundredth
7:thousandth
Answer:
D. $56
Step-by-step explanation:
Sandra's taxable income is $39,250.
That amount works for range 2 ($39,250 - $39,300), so her tax is $5,944.
Sandra paid $6,000 in FWT (federal withholding tax), which is greater than $5,944, so we need the refund here.
Subtract 5,944 from 6,000 to get the refund.
6,000 - 5,944
We can go on ahead and just make this 100 - 44 (5,900 - 5,900 = 0).
100 - 44
Her refund is $56.
