bayside insurance offers two health plans.Under plan A, Gisselle would have to pay the first 110 dollars of her, plus 25% of the rest. Under plan b, giselle would pay the first 230dollars , but only 20 % of the rest.for what amount of medical bills will plan b save gissselle money? assume she has over 230 dollars worth of bills. Gisselle would save with plan bif she had more then $ in bills.

Let X be the bill total amount needed for the outofpocket net costs to be equal.
110 + 0.25X = 230 + 0.20 X
120 = 0.05 X
Solve for X
If total costs exceed X, plan B is the better deal.
