Ruiz invests $55 at a simple interest rate of 4%. How much interest will he earn after 5 years?

1 answer:

7 0

To answer this item, I assume that it is compounded yearly such that the amount of interest (I) from the given present worth (P), interest rate (i) and the number of years (n) is calculated through the equation,
I = P x (1 + i)^n - P
Substituting,
I = ($55) x (1 + 0.04)^5 - $55
I = 11.91
The answer is nearest to the first choice, $11.

notka56 [123]

Set the equations equal to each other because you need to find when they will be the same.

$256 - 3x = 384 - 5x$
Add 5x to each side and subtract 256 from each side to get the variable alone.

$2x = 128$
Divide by 2.

$x = 64$
