how can i calculate in matlab

we borrowed $1000 at a 10% anual intrests rate. if we do not makre a payment for 2 years, and assuming there is no penalty for non payment, how much do we owe now?

This isn't really a MATLAB problem. It is a finance problem. Also, it seems like homework. What have you already tried?

[lokesh m]

the answer isws 1210

[Alfred Jones Arokiaraj]

wrong answer . try in CI. answer will be 1.2100e+03

@Alfred Jones Arokiaraj

At the MATLAB command prompt give the command

format long g

now ask to display the result again.

Answer 1

[Atsushi Ueno]

simple interest:

1000 + (1000 * 0.1) * 2

compound interest:

1000 + 1000 * 0.1 + (1000 + 1000 * 0.1) * 0.1
or
1000 * (1 + 0.1) ^ 2

as function

simple interest:

function current = simple_interest(debt, rate, period)
  current = debt + (debt * rate) * period;
end

compound interest:

function current = compound_interest(debt, rate, period)
  current = debt * (1 + rate) ^ period;
end

Answering homework question with full solution is discouraged in this forum.

I'm sorry. I'll be more careful from now on.

[Neha Jaiswal]

thank you. it was first question so i was unable to understand.

Answer 2

[Roopesh R Peter]

Compound the interest once a year:

debt = 1000 + 1000 * 0.1 + (1000 + 1000 * 0.1) * 0.1

Answer 3

[Shivani Dubey]

p = 1000
r = 10/100
n= 1
t = 2


S =(1.1)^2
debt = p* S

thanks i had a tried a different methode and it has the same result but it was rejected when i submitted it to COURSERA but when i tried to you know simplify it like you did it worked

Thanks.

Answer 4

The problem is simple and related to finance,

Borrowed_money = 1000;
Interest_rate = 10/100;
Delay_year = 2;
 
debt = Borrowed_money*(1+Interest_rate)^Delay_year
