\frac{cos(a-b)}{cos(a)cos(b)} =  \frac{cos(a)cos(b)+sin(a)sin(b)}{cos(a)cos(b)} = 1+ \frac{sin(a)sin(b)}{cos(a)cos(b)} =1+tan(a)tan(b)

Note that I used these identities :cos(a-b)=cos(a)cos(b)+sin(a)sin(b) and  tan(a)= \frac{sin(a)}{cos(a)}

If the purchase price for a house is $445,500, what is the monthly payment if you put 5% down for a 30 year loan with a fixed ra
Lemur [1.5K]

The monthly payment if we put 5% down for a 30-year loan with a fixed rate of 6.25% is (B) $2,605.87 (approx).

<h3>What is a loan?</h3>
  • A loan is the lending of money by one or more individuals, organizations, or other entities to other individuals, organizations, or other entities in finance.
  • The recipient (i.e., the borrower) incurs a debt and is typically required to pay interest on that debt until it is repaid, in addition to repaying the principal amount borrowed.
  • The document evidencing the debt will typically include information such as the principal amount borrowed, the interest rate charged by the lender, and the date of repayment.
  • A loan is the temporary reallocation of the subject assets between the lender and the borrower.

To find the monthly payment if we put 5% down for a 30-year loan with a fixed rate of 6.25%:

  • The purchase price is = $445500
  • 5% is down payment = 0.05 × 445500 = 22275
  • Loan amount is = 445500 - 22275 = 423225
  • The EMI formula is = [p × r (1+r)ⁿ]/[(1+r)ⁿ-1]
  • p = 423225
  • r = 6.25/12/100=0.0052
  • n = 30 × 12 = 360
  • Putting the values in the formula we get:
  • [423225 × 0.0052 × (1.0052)³⁶⁰]/[(1.0052)³⁶⁰-1]
  • = $2603.17

Therefore, the monthly payment if we put 5% down for a 30-year loan with a fixed rate of 6.25% is (B) $2,605.87 (approx).
