Plz me i am having trouble on this problem

Amuffin recipe, which yields 12 muffins, calls for cup of milk for every 1 cups of flour. the same recipe calls for cup of coconut for every cup of chopped apple. to yield a batch of 30 muffins, how much flour will be needed in the mix?

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

What is the total area of the figure?
