(Round to the nearest whole number)
------------------------------------
Let "x" be the amount of the bills.
Plan A: A(x) = 100 + 0.25x
Plan B: B(x) = 110 + 0.20x
------------------------------
For what amount of medical bills will plan B save Giselle money?
110 + 0.20x < 100 + 0.25x
0.05x > 10
(5/100)x > 10
x > (100/5)*10
x > $200
-----------------------------------------------
