# graph and solve the system of inequality

CheckPoint

11) Bayside Insurance offers two health plans. Under plan A, Giselle would have to pay the first $190, plus 40% of the rest. Under plan B, Giselle would pay the first $220, but only 30% of the rest. For what amount of medical bills will plan B save Giselle money? Assume she has over $220 in bills.

Giselle would save with plan B if she had more than $__ in bills. (round to the nearest whole number)

14) Solve and graph

-8?4x+4 and 4x+4<16

The solution is {x __ ? x < __}

15) Solve:

-6<x+5<10

The solution is {x l __ <x<__}

16) Solve

-11 ? 4 x -4 ? -3

The solution is {x l __ ? x ? __}

(Type an integer or a fraction)
