Question 858879
A health insurance company offers two plans. 
With plan A you pay the first $150 of you medical bills and they pay 80% of the rest.
A(x) = 150 + 0.8x
----------------------------- 
With plan B you pay the first $250 of your medical bills and they pay 90% of the rest.
B(x) = 250+0.9x
----------------------------- 
For what amounts of medical bills will plan B save you money?
-------
Solve: B(x) < A(x)
250+0.9x < 150+ 0.8x
100< -0.1x
x < -100/0.1
x < -10000
======================
Note: This answer says plan B will never save you money.
