The Jones family plans to borrow $19,000 for 12 years. If the interest rate is 4.25%, how much will the family pay in interest a

valentinak56 [21]

19000 × 12 × 4.25 = 969000

969000 ÷ 100 = 9690

So, 19000 - 9690 = 9310 is the principal.

9690 is the interest.

Hope this helped! :)

Mathematics Inclined Week #1: Difficult Category

Whitepunk [10]

Let $n=1$ . Then the statement says

$1(1!)=1$
$(1+1)!-1=2!-1=2-1=1$

so it holds for the base case.

Assume it holds for $n=k$ , i.e. that

$1(1!)+2(2!)+3(3!)+\cdots+k(k!)=(k+1)!-1$

and use this to show it holds for $n=k+1$ . You have

$1(1!)+2(2!)+\cdots+k(k!)+(k+1)(k+1)!=(k+1)!-1+(k+1)(k+1)!$
$=(k+1)!(1+k+1)-1$
$=(k+1)!(k+2)-1$
$=(k+2)!-1$

which is what you needed to show, so the statement is true.
