They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.

Hope this helps.

If the present value of my investment is $8,000 and the rate of interest is 12% compounded annually, what will the value be afte

Dvinal [7]

Answer:

$17,685.45

Step-by-step explanation:

We will use the compound interest formula to solve this:

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

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

The first step is to change 12% into a decimal:

12% -> $\frac{12}{100}$ -> 0.12

Next, lets plug in the values:

$A=8,000(1+\frac{0.12}{1})^{1(7)}$

$A=17,685.45$

After 7 years, you will have $17,685.45
