290 is 10 times as much as?
katrin2010 [14]
I'm pretty sure it's 29 . . . A way to remember is that when you multiply a number by ten, add a zero. For example, 34 x 10 is 340. Just add the zero!

Use the compound interest formula to determine the final value of the following amount. $1900 at 10.4% compounded monthly for 4.
nikklg [1K]

Answer:

$3027.80

Explanation:

The compound interest formula is the following.

A=P(1+\frac{r}{n})^{nt}

where

A = final amount

P = principle amount

r = interest rate / 100

n = number of compounds per interval

t = time interval

Now in our case,

A = unknown

P = $1900

r = 10.4/100

n = 12 months / year ( because the interest is compounded monthly)

t = 4.5 yrs

Therefore, the compound interest formula gives

A=1900(1+\frac{10.4/100}{12})^{12*4.5}

Using a calculator, we evaluate the above to get

\boxed{A=\$3027.80}

which is our answer!
