Question

3. The electricity accounts of residents in a very small town are calculated as follows: e if 500 units or less are used the cost is 2 cents per unit; . if more than 500, but not more than 1000 units are used, the cost is $10 for the first 500 units, and then 5 cents for every unit in excess of 500; . if more than 1000 units are used, the cost is $35 for the first 1000 units plus 10 cents for every unit in excess of 1000; e in addition, a basic service fee of $5 is charged, no matter how much electricity is used. Write a program which enters the following five consumptions into a vector, and uses a for loop to calculate and display the total charge for each one: 200, 500, 700, 1000, 1500.

Can you make matlab solve it?

Answer 1

MATLAB Code:

% Script that calculates the electricity bill

% Input vector
ipVec = [200, 500, 700, 1000, 1500];

% Iterating over each value
for i=1:5
% Getting value
units = ipVec(i);
  
% Set cost to 0 initially
cost = 0;
  
% Calculating bill
if units <= 500
cost = units * 0.02;
elseif units > 500 && units <= 1000
cost = 10 + ((units-500 * 0.05));
elseif units > 1000
cost = 35 + ((units-1000 * 0.10));
end   
  
% Adding service fee
cost = cost + 5;
  
% Printing results
fprintf("\n For %d units, ElectricBill is $%.2f \n", units, cost);
  
end % for end

>>electricityBill For 200 units, ElectricBill is $9.00 For 500 units, ElectricBill is $15.00 For 700 units, ElectricBill is $690.00 For 1000 units, ElectricBill is $990.00 For 1500 units, ElectricBill is $1440.00
