Pretty straightforward stuff. You should be able to do it yourself.

A: Cost: The fixed daily operating cost, plus $0.60 for each of the x portions sold.

(Or, to make it better algebraic form, $0.60 for each of the x portions sold, plus the fixed daily operating cost. That is, "y = mx+b" instead of "y = b + mx").

B: Revenue: $2 for each of the x portions sold.

C: She breaks even when her revenue is equal to her cost. Set the two equations from A and B equal to each other and solve to find the value of x (number of portions sold) that makes revenue = cost.

D: Plug the value from C into the revenue function from B.
