12 divided by 1/4

12    x  4                       = 48

A family wants to save for college tuition for their daughter. What continuous yearly interest rate r% is needed in their saving
sergey [27]

Answer:

The continuous yearly interest is  22.5% per year.

Step-by-step explanation:

Continuous yearly interest:

Continuous yearly interest is defined as the sum of the interest comes from principle and the interest comes from interest.

The formula for continuous interest yearly is

A=Pe^{rt}

where A = The final amount =$110,000

P= principle =$4,700

r= rate of interest

t= time (in year)= 14 years

\therefore 110,000= 4,700e^{r\times 14}

\Rightarrow e^{14r}= \frac{110,000}{4,700}

Taking ln both sides

\Rightarrow ln e^{14r}= ln(\frac{110,000}{4,700})

\Rightarrow {14r}= ln(\frac{1100}{47})

\Rightarrow r=\frac{ln( \frac{1100}{47})}{14}

\Rightarrow r = 0.225  (approx)

The continuous yearly interest is 0.225 = 22.5% per year.

I will give brainiest to whoever answers correctly !!
Scrat [10]

Answer:

15,894.06

Step-by-step explanation:

HI there!

This is a compound interest question, so we will use the formula

x = p(1+\frac{r}{n})^n^t

P being our principle amount, $15,000 in this case,

R being our rate, or 1.25

N being our compound rate, which is semiannually, or twice a year.

T is our time, being 3.

After plugging these values in, we get

15,894.06

I hope this helps!
