Bayside Insurance offers two health plans. Under plan A ,Giselle would have to pay the first $190 of her medical bills,plus 30% of the rest.Under plan B ,Giselle would pay the first $220, but only 20% of the rest. For what amount of medical bills will plan B save Giselle money ? Assume she has over $220 in bills

If she has $220 in bills, she pays for the whole thing in Plan B, but less than that for Plan A. Otherwise...

$190 + .3x > $220 + .2x

Solve for x.

I hope this helps.
