Help with this word problem please! Bayside Insurance offers two health plan A, Giselle would have to pay the first $80.00 of her medical bills, plus 25% of the rest. Under plan B, Giselle would pay the first $90.00 but only 20% of the rest. For what amount of medical bills will plan B save Giselle money? Assume she has over $110 in bills. Giselle would save with plan B if she had more than $? in bills. (Round to the nearest whole number) Thank you!!!
