---------------------------
Under plan B, Giselle would pay the first $240, but only 25% of the rest.
B(x) = 240 + 0.25x where x is amount over 240
-----------------------------

Solve: 240+0.25x < 180+0.4x
60 < 0.15x
x > $400

Let represent the amount of the medical bills. Then she is either going to pay or . The total amount of medical bills that makes these two expressions equal is the break-even amount. Less than the break even, the 180/40 plan is best. More than the break-even, the 240/25 plan is best.



Solve for to find the break-even amount.
