function

 if consump<=160
    cost= cosump*33;
 elseif (consump>161) && (consump<=300)
    cost= 160*33+(cosump-160)*72;

Best Answer

You have a repeated typographical error, typing ‘cosump’ instead of ‘consump’.
See if this corrected version of your function works:
function cost = calc(consump)
if consump<=160
    cost = consump*33;
elseif (consump>161) && (consump<=300)
    cost= 160*33+(consump-160)*72;
end
end
