Question 410974
Under plan A, Giselle would have to pay the first $60 of her medical bills, plus 25% of the rest.
 Under plan B, Giselle would pay the first $210, but only 20% of the rest.
 For what amount of medical bills will plan B save Giselle money? Assume she has over $210 in bills.
:
Let m = amt of the medical bill
:
Cost of A: .25(m-60) + 60
Cost of B: .20(m-210) + 210
:
Cost of A > Cost of B
.25(m-60) + 60 > .20(m-210) + 210
Find m
.25m - 15 + 60 > .20m - 42 + 210
.25m + 45 > .20m + 168
.25m - .20m > 168 - 45
.05m > 123
m > {{{123/.05}}}
m > $2460.00 
Medical bills greater than $2460, plan B would be cheaper
