Bayside insurance offers Giselle a two part insurance coverage. She has to pay the first $50, plus 40% of the remaining bill. How much would her medical bills be in bills in order for paln B to save her money?

You need to explain "Plan A" in order to compare Plan B.

You have not done that.

To determine how much Giselle's medical bills would need to be in order for plan B to save her money, we can set up an equation.

Let's assume Giselle's total medical bill is represented by X. According to the plan, she has to pay the first $50, and then 40% of the remaining bill.

So for plan B, Giselle would pay:
$50 for the first part, plus
40% of the remaining bill (0.40X - 50).

The total amount she would pay under plan B is $50 + 0.40X - 50.

Now, let's compare the total amount Giselle would pay under plan B with the total amount she would pay under a different plan, plan A.

If plan A is cheaper, then the total amount she would pay under plan A must be less than the total amount she would pay under plan B.

Let's assume under plan A, Giselle would pay a total amount Y. Therefore, we can set up the following inequality:

Y < $50 + 0.40X - 50

Simplifying the inequality, we have:

Y < 0.40X

This means that Giselle's total bill, X, would need to be greater than Y/0.40 in order for plan B to save her money.

So, if you know the total amount Giselle would pay under plan A or have a budget in mind, divide that amount by 0.40 to find the minimum medical bill amount, X, for plan B to be more cost-effective.
