=+k. Use what you have calculated in (i) and (j) to verify that profit is indeed the same for a firm whether it uses the f or the g technology when price is p* (when the rest of the parameters of the problem are as we have specified them in (i) and (j)). (Note: If you rounded some of your previous numbers, you will not get exactly the same profit in both cases, but if the difference is small, it is almost certainly just a rounding error.)
