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

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

You're probably typing F5 or hitting the green run triangle to run the code. Doing this does not pass in any value for consump. You would need to have a line of code, either in the command window or an m-file, where you pass in a value. For example, for 50:
cost = calc(50);
