Mara found the length of time of an investment. the principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. mara made an error in her work. what is the error?

Respuesta :

Step-by-step explanation:

Since we have given that

Principle of investment= $4300

Interest rate = 6.2% p.a

So, the interest made is given by

[tex]6.2\%\text{ of }4300\\\\=\frac{6.2}{100}\times 4300\\\\=\$266.60[/tex]

The error was that Mara divided 6.2 by 10 instead of dividing by 100.

So, she made a mistake.

Error margin is given by

[tex]2666-266.60\\=2399.4[/tex]
