Question 325756
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the amount of the medical bills.  Then she is either going to pay *[tex \Large 0.40x\ +\ 180] or *[tex \Large 0.25x\ +\ 240].  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.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.40x\ +\ 180\ =\ 0.25x\ +\ 240]


Solve for *[tex \Large x] to find the break-even amount.
