Under paln 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.
Answer provided by our tutors
let x represent the amount that makes plan B better.
200 + 0.25(x - 200)≥ 210 + 0.2(x - 210)
200 + 0.25x - 50 ≥210 + 0.2x - 42
0.25x - 0.2x ≥210 - 42 - 200 + 50
0.05x ≥18
x ≥360
plan B will save money if the amount is $360 or more
