USING MATLAB

For this problem you will be creating a "tip table" that could be used to look up an amount to leave as a tip given the restaurant bill. In addition to the column for the bill, the table will contain columns for 15%, 18%, and 20% tips. Create and display a matrix with four columns: column 1 contains bill totals from $5 to $100 in increments of $5 column 2 contains the tip amount if the tip is 15% of the bill column 3 contains the tip amount if the tip is 18% of the bill column 4 contains the tip amount if the tip is 20% of the bill If you've constructed your matrix correctly, when it is displayed, the first few lines will look like: To receive full credit, you must make use of MATLAB's matrix and vector creation and manipulation abilities, e.g., you cannot enter the first column in element by element, columns 2 through 4 should be calculated using column 1 (ie., if you decided to modify the tip table to go from bill totals of $2 to $50 in increments of $3, exactly one line of the code you wrote would need to be changed).

Explanation / Answer

%matlab code

initialBill = 5;
bill = [];
i = 1;
while initialBill <= 100
bill(i) = initialBill;
initialBill = initialBill + 5;
i = i + 1;
end

tipMatrix = zeros(length(bill),0);

for i=1:length(bill)
% total bill
tipMatrix(i,1) = bill(i);
% 15 percent tip
tipMatrix(i,2) = 0.15*bill(i);
% 18 percent tip
tipMatrix(i,3) = 0.18*bill(i);
% 20 percent tip
tipMatrix(i,4) = 0.20*bill(i);
end

disp(' BILL Tip(15%) Tip(18%) Tip(20%)');
disp(tipMatrix);
%{
output:
