<h3>Answer :- </h3>

  • 24 years

<h3>Solution :- </h3>

  • Let the age of victor be X .
  • and, the age of Mr.Smith be = 81 + x

♧ <em>So, after 3 years = x+81 +3</em>

  • 81 + 3 + x = 4 ( x + 3 )
  • 84 + x = 4x + 12

♧ <em>now grouping the variables and constants together we get,</em>

  • 4x-x=84-12
  • 3x = 72
  • x = 72/3
  • x = 24

♧ <em>Thus, Victor's present age is 24 yrs.</em>

Answer:

<u>Victor's age = 24 years old</u>

Step-by-step explanation:

Let age of Mr. Smith = x and age of Victor = y.

According to the question, we can find two equations.

=> 1) x = y + 81

=> 2) x + 3 = 4(y + 3)

Substituting value of x in (1) to (2)

y + 81 + 3 = 4y + 12

3y = 72

y = 24

<u>Victor's age = 24 years old</u>

Danielle bought a house for $215,000. She financed $189,375 of the purchase price with a 15-year-fixed-rate mortgage with a 6.1%
Brilliant_brown [7]
Total cost of the house = $215,000
Amount financed through mortgage = $189,375
Amount paid through other means (such as cash) = 215,000-189,375 = $25,625
Rate = 6.1% = 0.061
Number of years = 15 years

Monthly payment, M = P[i(1+i/12)^12*15]/[(1+i/12)^12*15 -1] = 189,375[0.061/12(1+0.061/12)^12*15]/[(1+0.061/12)^12*15 - 1] = $1,608.30
Total amount paid = $25,625 + (M*12*15) = $25,625 + $289,494.56 = $315,119.56

Seems the options given don't match the correct answer.
