You can put this solution on YOUR website! Bayside Insurance offers two health plans. Under Plan A, Sam would have to pay the first $80 of his medical bills, plus 35% of the rest. Under Plan B, Sam would pay the first $230, but only 20% of the rest.
 :
 Let b = amt of the medical bill
 Let p = amt he has to pay after insurance pays
 :
 Write an equation for plan A
 p = .35(b-80) + 80
 :
 Write an equation for plan B
 p = .20(b-230) + 230
 :
 For what amount of medical bills will Plan B save Sam money?
 Assume he was over $230 in bills.
 Sam would save with Plan B if he had more than $_____ in bills.
 :
 Plan A amt > Plan B amt
 .35(b-80) + 80 > .20(b-230) + 230
 .35b - 28 + 80 > .20b - 46 + 230
 .35b + 52 > .20b + 184
 .35b - .20b > 184 - 52
 .15b > 132
 b >
  b > $880, when his bill exceeds $880, he would save money with plan B
 :
 :
 It will help you understand, if you substitute 880 for b in both equations
 and find out the actual amt he will pay
