Question

Nadal invests $5,678 at an annual interest rate of 4.5 percent for 6 years. For which variable can Nadal substitute the value 5,678 in the simple interest formula?

Answer 1

Step-by-step explanation:

He can substitute it for Principal.

Principal =$5,678

rate percent = 4.5%

Time period = 6 years.

For finding Simple interest :

$=\:\Large\frac{P×R×T}{100}$

$=\:\Large\frac{5,678×4.5×6}{100}$

$\large\boxed{S.I=1533.06}$

To find amount :

$Amount=Principal+Simple\:interest$

$A=5,678+1533.06$

$\large\boxed{A=7211.06}$

He will get $1533.06 as Simple interest in 6 years at 4.5% rate.

Answer 2

Step-by-step explanation:

$simple \: interest \: = \: \frac{prt}{100}$

$\: \: \: \: \: = \frac{5678 \times 4.5 \times 6}{100}$

$\: \: \: \: \: = 1533.06$

$amount \: recieved = p + interest$

$\: \: \: \: \: = 5678 + 1533.06$

$\: \: \: \: \: = 7211.06$
