Answer
$A(2) \approx 2145.02$
$A(4) \approx 2300.5$
$A(12) \approx 3043.9$
Work Step by Step
We are given
$P=\$ 2000$
$r=0.035$
We use the formula for continously compounded interest with
a. $t=2$
$A(2)=2000e^{(0.035)2}=2000e^{(0.07)} \approx 2145.02$
b. $t=4$
$A(4)=2000e^{(0.035)4}=2000e^{(0.14)} \approx 2300.5$
c. $t=12$
$A(12)=2000e^{(0.035)12}=2000e^{(0.42)} \approx 3043.9$
