Question 282163: I need help with this question, I have worked it several times and still fail to solve it properly:
Bayside Insurance offers two health plans. Under Plan A, Giselle would have to pay the first $100 of her medical bills plus 40% of the rest. Under Plan B, Giselle would have to pay the first $220 of her bills plus 25% of the rest. For what amount of medical bills will Plan B save Giselle money? Assuming she has more than $220 in bills.
Thanks!

plan a
100+40(x-100)
plan b
220+25x(x-220)
100+40(x-100)=220+25x(x-220)
when x >220.85 plan b is cheaper
