If a person invests $290 at 6% annual interest, find the approximate value of the investment at the end of 15 years.

$261

Step-by-step explanation:

Simple equation to remember.

I = PRT

In this case, "I" means investment, "P" means principal, a fancy term for saying the starting money, "R" means rate in decimal form (just move the decimal two places to the left to convert the percent to decimal), and "T" means time, which is usually in years.

All you do is just plug in 290 as P, 0.06 as R, and 15 as the T, and then you multiply that all together to get.

However, this is only the simple investment equation, there are other equations such as the compound equation used for interest. I'm assuming you're only using the normal interest equation.

a² + b²= c²

24² + 7² = c²

c= 25

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
