Bayside insurance offers two health plans. Under plan A, Giselle would have to pay the first$70 of her medical bill, plus 30% of the rest. Under plan B, Giselle would pay the first$250, but only 25% of the rest.For what amount of medical bills will plan B save Giselle? Assume she has over $250 in bills.Giselle would save with plan B if she had more than $? in bills.
when is .3x + 70 = .25x + 250 ?
