Help with Bake Sale Pricing?

Bake sales are tough. I wouldn't charge over a dollar for the cookies and brownies. Only because it's not a store bought brownie or cookie so people aren't compelled to buy them as much. Not sure why but that's just how it goes. I would charge at least $0.50 for the lemonade because as I can imagine it's not a fully filled big cup. If it is then, be my guest and charge $1! For the fruit salad I would say charge $3-4.50 for it.
