im not good with word problems. Can you help me with this? bayside insurance offers two health plans under plan a, giselle would have to pay the first $130 of her medical bills, plus 35% of the rest under plan b, giselle would pay the first $190, but only 30% of the rest. For what amount of the medical bills will plan b save giselle money? assume she has over $190 in bills

So what you want is for x - 130 - 0.35(130 - x) > x - 190 - 0.3(190 - x) Does that make sense?

Actually the equation for this problem would be a little different. Since you don't know how much her medical bills will be, make that x. A second unknown is how much she will pay, so make that y. You want to set up an equation for each plan where the amount she has to pay (y) is (=) the fixed amount for each plan ($130 for plan a and $190 for plan b) and (+) a percentage (.35 for plan a and .3 for plan b) of (multiplication) the rest (which would be the total beyond what was already paid: x-130 for plan a and x-190 for plan b). The problem asks you to find when y is greater for plan a than plan b. That is when you want to set up an inequality with the two equations with the first being greater than the second and solve algebraically. Good luck!
