two health plans. Under plan A, Amy would have to pay the first $60 of her medical bills, plus 30% of the rest. Plan B would pay the first $140, but only 20% of the rest. For what amount of medical bills will plan B save Giselle money? Assume she has over $140 in bills.
A= $60 +30x
B= $140 + 20x
then I get confused

  • Math -

    PlanAcosts=60+(Bills-60)*.30
    PlanBcosts=140+(Bills-140)*.2
    set them equal, and solve for Bills.

    Thanks Bobpursley for the push in the right direction
