Answer:

P=163,487,500

Step-by-step explanation: P=Ae^(kt)

151000000=145000000*e^(k5)

151000000/14500000=e^(k5)

1.04137931=e^(k5)

Ln 1.04=Ln e^(k5)

0.04=k5

k= 0.008

P=145,000,000*e^(.008*15)

P=145,000,000*e^0.12

e=2.71828

P=145,000,000*1.12749685

p=163,487,500

You deposit $1,200.00 into an account and in three years of simple interest you have $1,380. What interest rate are you receivin

Tcecarenko [31]

Since simple interest doesn't involve compounding, the same amount gets added on every year. So, the equation for the simple interest received is $I = Prt$ , where $I$ is the total interest, $P$ is the original deposit (or "principal"), $r$ is the interest rate, and $t$ is the time passed in years.

Plugging in our values, we can solve for the interest rate:

$I = Prt$
$\$1380 - \$1200 = (\$1200)(r)(3 years)$
$\$180 = (\$1200)(r)(3 years)$
$r = .05 = \bf 5 \%$
