Question

in matlab

It takes approximately 11,000 liters (3,000 gallons) [BBC] to make a pair of jeans. To make a shirt it takes about 2700 liters (713 gal), and for socks I assume it is shirt/12 which is 225 Liter. I assume everyone has at least 7 extra jeans, 12 extra shirts, and 1 extra sock.

1. Fill out the 3^rd column of the following table based on the first two columns using element by element operation.
2. Find the total amount of water (in liter) used in column 3 using the sum() function.
3. 2800 Liter of water is needed for an avocado tree per year, how many avocado trees could you water with what you found in b
4. I did the math (using how much water avocado and lemon and tomato needs) and discovered that for 1500 liter of water you can make 1 m³ of Guacamole. What percentage of your room can be filled with Guacamole using what you found in b. ( The usual size of a room is 5x6x3 meters which leads to 90 m³)
   Number of Extra Item Liter of water/unit Total water consumption per category 7 _(Jean) 11,000 12 _(Shirt) 2700 1 (Sock) 225

I have provided both the text and the screenshot for your better understanding. The screenshot also has some comments for your help. Please note that these are script files which are to be saved as "function_name.m" in your MATLAB root directory.

pilot.m

fan.m x pilot.mx + function pilot() 1 2 3 4 5 - 6 7 SUBPART A water = [11000;2700;225]; storing water amount in liters extra = [7;12;1]; storing item number tot = zeros (3,1); $column 3 initialize for i = 1:3 tot (i) = water(i) extra(i); end disp('Column 3 entries'); disp (tot); 8 9 LO 11 - 12 13 14 - SUBPART B amt = sum (tot); fprintf ("Total water used is $d litres\n", amt); 15 - 16 17 18 - 19 SUBPART C tre = amt/2800; fprintf("Number of avocado trees that can be planted is sd. \n", floor (tre));| 20 21 22 - SUBPART D vol = amt / 1500; fprintf("Total volume of room that can be filled with Guacamole is $.2f $$\n", vol*100/90); end 23 24

function pilot()

%SUBPART A
water = [11000;2700;225]; %storing water amount in liters
extra = [7;12;1]; %storing item number
tot = zeros(3,1); %column 3 initialize
for i = 1:3
tot(i) = water(i) * extra(i);
end
disp('Column 3 entries');
disp(tot);

%SUBPART B
amt = sum(tot);
fprintf("Total water used is %d litres\n",amt);

%SUBPART C
tre = amt/2800;
fprintf("Number of avocado trees that can be planted is %d. \n",floor(tre));

%SUBPART D
vol = amt / 1500;
fprintf("Total volume of room that can be filled with Guacamole is %.2f %%\n",vol*100/90);
end

OUTPUT

>> pilot Column 3 entries 77000 32400 225 Total water used is 109625 litres Number of avocado trees that can be planted is 39. Total volume of room that can be filled with Guacamole is 81.203
