Finding the value of c

N = 30

% Years

r = 0.12

% yield precentage

power_kwh_per_year = 157680000

c = 0.02:0.01:0.1

cost_per_kwh = 0.02;

CF = power_kwh_per_year.* (c - cost_per_kwh);

% Cash flow after the first year

NPV = -57000000

% The cost on year 0

% NPV = Net Present value

for i = 1:N

NPV = NPV + ((CF) ./ ((1 + r).^i));

end

Im trying to find what the value of c is when NPV = 0, any tips on how i can do that?

We know that the value is between 0.06 and 0.07
