Mathematics

Answer: Look at it this way, you are adding 4.2, .5 times. So if you find what 1.5 is of 4.2 you then add that to 4.2. The 1 stands for how many times the number is being multiplied by. So in this case the number is only being multiplied once. Then we move onto the decimal point which says that the number is being multiplied by .5 times. This means that 2.1 (which is half of 4.2) is being added onto 4.2. Hope this makes sense. I always use a calculator for multiplying so its hard to put the process into words haha.

Suppose you invested $1500 in an ac count that paid an annual of 3% compound monthly. How much would you have after 1 year?
Sati [7]

Answer:

1545.62

Step-by-step explanation:

The calculation of compound interests uses this formula:

<h2>A = P (1 + \frac{r}{n} )^{n*t}</h2>

Where  A = total amount, P = principal or amount of money deposited, r = annual interest rate, n = number of times compounded per year  and t = time in years.

So, if we plug-in the numbers of the problem we have:

<h2>A = 1500 (1 + \frac{0.03}{12} )^{12*1}</h2>

Which gives us:

A = 1500 * 1.0025^{12} = 1500 * 1.030416 = 1545.62

For a grand total of 1,545.62 including capital and interests.
