Question 205543
Bayside Insurance offers two health plans. 
Under Plan A, Sam would have to pay the first $170 of his medical bills, plus 35% of the rest.
Under Plan B, Sam would pay the first $210, but only 30% of the rest.
----------------------- 
For what amount of medical bills will Plan B save Sam money?
Let the medical bills be "x" dollars:
Plan A cost: 170+ 0.35(x-170)
Plan B cost: 210+ 0.30(x-210)
---
Inequality:
Plan B < Plan A
210 + 0.30(x-210) < 170 + 0.35(x-170)
0.70*210 + 0.30x < 0.65*170 + 0.35x
0.05x > 36.6
x > $730
----------------------------------------------------




 Assume he was over $210 in bills. Sam would save with Plan B if he had more than $_730.00____ in bills.
