Suppose you want to start saving for retirement. You decide to continuously invest $20000 of your income each year in a risk-fre
Korvikt [17]

Answer:

Following are the solution to the given points:

Step-by-step explanation:

p= amount at any time

then \frac{dp}{dt}=0.07 p

p=p_0 (1+e^{0.07 t) \\\\

P_0=\ principle \ amount \\\\  interest \ =p-p_0=p_0e^{0.07t}\\\\ p=y\frac{dy}{dt}=0.07y_0

at time = t\ years

\frac{dp}{dt}\\\\c_0=\$ \ 20000\ year\\\\p \to p+dp\\\\ dp=0.07p+c_0

y= amount at any times

\frac{dy}{dt}=0.07y+c_0\\\\dt= \frac{dy}{c_0+0.07y}

For point a:

\frac{dy}{dt}=20000+0.07 y

For point b:

\frac{dy}{20000+0.07 y}=dt\\\\\frac{1}{0.07}|n(\frac{0.07y+20000}{20000})=t\\\\\frac{0.07y}{20000}+1=e^{0.07t}\\\\y=7.1428\times 10^4[e^{0.07t} -1]\\\\y=\frac{20000}{0.07}[e^{0.07t}-1]\\\\

For point c:

y(30)=827391.75
