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 < __}
