She estimates it takes $3.50 worth of ingredients and $6 of labor to make a cake. She plans to charge customers $16 per cake, and she will only sell whole cakes. _2 points Calculate how many cakes Rita has to sell to break even cakes/month 2 points Rita has discovered that there are 3D food printers that can be used to decorate cakes.
