amistre64 · Answer

190 +(bill-190)(.3)

210 +(bill - 210)(.25)

amistre64 · Answer

A=bill(.3) +190(.7)

B=bill(.25) + 210(.75)

anonymous · Answer

Plant A=0.3x+190

Plant B=0.25x+210
0.25x+210=0.3x+190
  210-190  =0.3x-0.25x
                10=0.05x
       10/0.05=x
             200 =x

She have to spent $200 amount medical bills will  save on plan B

amistre64 · Answer

A=bill(.3) +133

B=bill(.25) + 157.50

A-B = 0


bill(.3-.25) +133-157.50 = 0

bill(.05) -24.50 = 0

bill = 24.50/.05 = 490

amistre64 · Answer

490(.30) + 133 = 280

490(.25) + 157.50 = 280 ...

anything over 490 she saves with plan b

anonymous · Answer

Let x equal the total medical expenses.  Equate the cash payouts for each plan and solve for x.$$190+\left(\frac{3}{10}\right)(x-190)\text{=}210+\left(\frac{1}{4}\right)(x-210) $$x = 490, the same as amistre64.
