Bayside Insurance offers two health plans. Under plan A, giselle would have to pay the first $130.00 of her medical bills, plus 25% of the rest. Under plan B, Giselle would pay the first $150, but only 20% of the rest. For what amount of meidcal bills will plan V save Giselle Money? Assume she has over $150 in bills.

Solve the equation
150 + 0.2 X = 130 + 0.25 X
X is the amount of bills.
20 = 0.05 X
x = 400 dollars is the breakeven point.
