Answer:

3, 50, 2

Step-by-step explanation:

By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.

3(n +25)= 5(10) +5(\frac{2}{5} n)

3(n +25)= 50 +2n

To find the value of n, expand the bracket on the left hand side:

3(n) +3(25)= 50 +2n

3n +75= 50 +2n

Bring all n terms to one side, constants to the other:

3n -2n= 50 -75

n= -25

Sam takes out a $167,000 mortgage for 20 years. He makes monthly payments and at the end calculates
cupoosta [38]

Answer:

The Annual rate of interest for the mortgage is 1.8%

Step-by-step explanation:

Given as :

The mortgage principal = p = $167,000

The time period of mortgage = t = 20 years

The Amount paid towards mortgage in 20 years = A = $240,141

Let the Annual percentage rate on interest = r % compounded annually

Now, <u>From Compound Interest method</u>

Amount = Principal × (1+\dfrac{\textrm rate}{100})^{\textrm time}

Or, A = p × (1+\dfrac{\textrm r}{100})^{\textrm t}

Or, $240,141 = $167,000 × (1+\dfrac{\textrm r}{100})^{\textrm 20}

or, \dfrac{240,141}{167,000} =  (1+\dfrac{\textrm r}{100})^{\textrm 20}

Or , 1.437 =  (1+\dfrac{\textrm r}{100})^{\textrm 20}

Or, (1.437)^{\frac{1}{20}} = (1+\dfrac{r}{100})

or, 1.018 = (1+\dfrac{r}{100})

Or, \dfrac{r}{100} =  1.018 - 1

Or, \dfrac{r}{100} = 0.018

∴ r = 0.018 × 100

i.e r = 1.8

So, The rate of interest applied = r = 1.8 %

Hence, The Annual rate of interest for the mortgage is 1.8%  Answer
