Question

Matlab help thank you

-Consider a person s yearly salary is 30k usd System 1: get 5% of your salary and put in a bank with 4% interest System 2:get 5% of your salary and match it with the same amount (another 5% from your employer) Calculate and plot over 30 years the amount of money you will get if you get 0% interest on system 2 ) for system 2 to become better than -Do another plot with different amount of interest (1%,2%, system 1 after 25 years

Answer 1

Plot 2:

%to compute the system 1 values
x=[]
x(1)=30*0.05
for i=2:30
    x(i)=x(i-1)+(x(i-1)*0.04)+(30*0.05)

y=[]
y(1)=(30*0.05)
for i=2:30
    y(i)=y(i-1)+(30*0.05)+(30*0.05)

%to plot the amount of money versus years
years=1:30

%create the plot of system 2

plot(years,y,'color','b');

xlabel('Years')

%make plot with different value of interest
