ANSWER

The second statement is the contrapositive of the first.

EXPLANATION

If we have the conditional statement,

$x\Rightarrow \: y$

Then the converse of this statement is
$y\Rightarrow \: x$

The inverse of this statement is
$\neg \: x\Rightarrow \neg \: y$

and the contrapositive of this statement is
$\neg \: y\Rightarrow \neg \: x$

The correct answer is C.

Answer:

$7,358

Step-by-step explanation:

Assuming the interest is compounded annually, the amortization formula is useful here.

A = Pr/(1 -(1+r)^-t)

A is the annual scholarship, P is the principal invested at rate r for t years.

A = $100,000(0.04)/(1 -1.04^-20) = $7,358.18

The university could give $7,358 in scholarships each year.
