Bayside Insurance offers two health plans. Under plan A, Giselle would have to pay the first $50 of her medical bills, plus 25% of the rest. Under plan B, Giselle would pay the first $150, but only 20% of the rest. For what amount of medical bills will plan B save Giselle money? Assume she has over $150 in bills.

  • algebra - ,

    costA=50+.25(total-50)
    costB=150+.20(total-150)

    so costB<costA
    put the equations in, and solve for total
    50+.25T-12.5<150+.2T-30

    .05T<150-30-50+12.5
    T<82.5/.05
    T<1650 check that.
