Donut You Know makes custom donuts for holidays throughout the year for fun and to help with marketing. The owners want to make a special batch of heart shaped donuts for Valentine's Day and need to determine how many to make. They sell the specialty donuts for $$3\mathrm{.}95$ each. However, the next day they are discounted to $$0\mathrm{.}50$ each. Custom donuts cost $$3\mathrm{.}25$ each to make $($labor and materials$).$ Donuts not sold on the holiday they are made for have to be packaged to be sold the next day. This incurs an additional $$0\mathrm{.}10$ of cost per donut.
