you deposited 8500 dollars in a savings account that earns a simple interest rate what interest rate do you need to be paid if y

anzhelika [568]

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=5\ years\\ P=\$8,500\\ A=\$10,093.75\\r=?$

substitute in the formula above

$10,093.75=8,500*(1+r*5)$

solve for r

$5*r=(10,093.75/8,500)-1$

$r=0.0375$

$r=3.75\%$

therefore

<u>the answer is</u>

the rate of interest is $3.75\%$

<h2><u>✎ </u><u>Answer:</u></h2>

<u /> $1\frac{1}{2}$ $batches$

➛➛➛➛➛

$\frac{1/2}{1} =\frac{3/4}{x}$

$\frac{1}{2} =\frac{3}{4x}$

$cross~multiply$

$4x=2(3)$

$\frac{4x}{4} =\frac{6}{4}$

$x=\frac{3}{2} =1\frac{1}{2}$
