It takes a baker earning $$9/$hour $1$ hour to make $100$ chocolate chip cookies. The recipe costs $$9\mathrm{.}25$ and uses $$1\mathrm{.}50$ in energy costs. The purchaser can order premade cookie dough at a cost of $$29\mathrm{.}50$; the pre$-$made tub yields $250$ cookies. The pre$-$made version uses only $$1\mathrm{.}00$ in energy costs, but the baker needs $1$ hours to make all $250$ cookies. What is the cost per cookie for the scratch version and for the pre$-$made version?$$
