if loop for checking package weights and to calculate shipping costs

package = input('Enter weight of package\n')

cost =15; % %15 for the two first lbs

if package <=2 %checks for packages equal or less than 2lbs

fprintf('Your total cost is $%.2f \n', cost)

elseif package >=70 % checks for packages over 70lbs

cost = cost + 15; % adds %15.00 when over 70 lbs

fiveperlb = (package - 2) * 5; %calculates additional %5.00 per lb after initial 2lbs

total_shipping = cost + fiveperlb; %sums up the total shipping cost

fprintf('The total shipping cost is $%.2f',total_shipping)

elseif package < 70 % checks for packages less than 70 lbs

fiveperlb2 = (package -2) * 5; %calculates additional %5.00/lb after initial 2lbs

total_shipping2 = cost + fiveperlb2; % sums up total shipping costs

fprintf('The total shipping cost is $%.2f', total_shipping2)

else package > 100

disp('Package weight exceeded, will not accept')

end

I can't seem to figure out how to get it to decline me when i input a weight higher than 100 lbs

Try this —

for package = [1 25 50 75 110]
package                                                 % Package Weight In Loop (Delete When Loop No Longer NEcessary)
% package = input('Enter weight of package\n')
cost =15; % %15 for the two first lbs
if package <=2 %checks for packages equal or less than 2lbs
    fprintf('Your total cost is $%.2f \n', cost)
    
elseif package >=70 & package < 100 % checks for packages over 70lbs
    cost = cost + 15; % adds %15.00 when over 70 lbs
    fiveperlb = (package - 2) * 5; %calculates additional %5.00 per lb after initial 2lbs
    total_shipping = cost + fiveperlb; %sums up the total shipping cost
    fprintf('The total shipping cost is $%.2f',total_shipping)
elseif package < 70 % checks for packages less than 70 lbs
    fiveperlb2 = (package -2) * 5; %calculates additional %5.00/lb after initial 2lbs
    total_shipping2 = cost + fiveperlb2; % sums up total shipping costs
    fprintf('The total shipping cost is $%.2f', total_shipping2)
else % package > 100
disp('Package weight exceeded, will not accept')
end

end

package = 1

Your total cost is $15.00 

package = 25

The total shipping cost is $130.00

package = 50

The total shipping cost is $255.00

package = 75

The total shipping cost is $395.00

package = 110

Package weight exceeded, will not accept

I will let you explore the changes I made to understand what I did and the reason the logic now works!
