I need help on this math project please help?

One dozen of plain cookies requires one pound of dough and the iced cookie requires .5 lbs of dough and .5 lbs icing. It takes about 0.1 hours to cook each dozen of plain cookies prep time and 0.15 for the iced cookies. No matter how many of each they make all can be sold. Profit for plain is 1.30 and iced is 1.80. Limitations- 110 lbs of dough and 30 lbs icing. They have room to bake a total ok 150 dozen cookies. Together they have 15 hours for prep time. I have to identify the variables write the constraints and profit equation. How many dozens of each type of cookie can be made to earn the largest profit how much cookie dough will be used how much icing how much prep time and how much space will they use
