Question 1092506
<br>Pretty straightforward stuff.  You should be able to do it yourself.<br>
A: Cost:  The fixed daily operating cost, plus $0.60 for each of the x portions sold.<br>
(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").<br>
B: Revenue:  $2 for each of the x portions sold.<br>
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.<br>
D: Plug the value from C into the revenue function from B.
