90 hundreds = how many thousands

alina1380 [7]

we know that

$90 hundreds=90*100\\ =9,000$

and

$one.thousand=1,000$

So

Divide

$9,000$ by $1,000$

$\frac{9,000}{1,000} =9$

therefore

The amount for the given data is found as, $\rm a = 2825(1+\frac{3.9}{12} )^{12t}$ .The given expression is true.

<h3>What is the amount?</h3>

The complete repayment of money at the end of the period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P is the annual payment=2827

r is the rate of interest = 3.9%

n is the time period=12

The formula for the amount is found as;

$\rm a = p(1+\frac{r}{n} )^{nt}$

Substitute the given value;

$\rm a = 2825(1+\frac{3.9}{12} )^{12t}$

Hence the given expression is true.
