Carmella is purchasing a $105,000 home and her bank is offering her a 30-
GREYUIT [131]

Answer:

$132.93

Step-by-step explanation:

We will use annuity formula, which is:

P=C[\frac{1-(1+r)^{-n}}{r}]

Where P is the loan amount

C is the monthly payment

r is the rate of interest [monthly]

n is the time period [in months]

Firstly, let's calculate her normal monthly payment (without purchasing points):

P is 105,000

C is what we need to find

r is the 0.045/12 = 0.00375

n is 12*30 = 360

Now, we have:

P=C[\frac{1-(1+r)^{-n}}{r}]\\105,000=C[\frac{1-(1+0.00375)^{-360}}{0.00375}]\\105,000=C[197.3612]\\C=532.02

So <u>monthly payment would be around $532.02</u>

<u />

Now,

With each point purchase, the interest rate goes down by 0.25%, so for 2 points it will be 4.5% - 2(0.25) = 4%

Also, since 20% downpayment, the loan amount would be (0.8)(105,000) = 84,000.

Now, putting these values into the annuity formula we have:

84,000=C[\frac{1-(1+0.0033)^{-360}}{0.0033}]\\84,000=C(210.4766)\\C=399.09

The <u>monthly payment would be around $399.09</u>

<u />

The amount that is lower is  532.02 - 399.09 = $132.93

Question Solve the equation. Check your solutions. ∣2x+1∣=∣3x−11∣
kirill [66]

Answer:

x=2 and x=12

Step-by-step explanation:

|2x+1| = |3x-11|

2x+1 = 3x-11

2x = 3x-12

-x = -12

x = 12

2x+1 = -(3x-11)

2x+1 = -3x+11

5x+1 = 11

5x = 10

x = 2
