Bayside insurance offers two health plans.Under plan A Giselle would have to pay the first $80 of her medical bills plus 40% of the rest. Under plan B Giselle would pay the first $210, but only 30% of the rest. for what amount of medical bills will plan B save Giselle money?

Assume she has over $210 in Bills

Answer 1

Seems like you aren't the only one having problems getting help today. More people asking questions than answering or helping answer.

Answer 2

I agree. I have had this problem all day.

Answer 3

So you need to look at it as an equation:
We have
M + d(C-M)
assuming that C > M, with C = cost, d = percent to pay, M equals minimal cost
Does that make sense?

Answer 4

Yes kind of...That is the formula we use to solve the problem?

Answer 5

ooooooooh, this is more interesting than that, sorry I misread

Answer 6

but, you can solve it with just a little more work, that's almost enough

Answer 7

I have a hard time with word problems, never fails. Especially in algebra

Answer 8

ahh, I totally understand, it's very common

Answer 9

so, you need to find when the two cost the same amount of money

Answer 10

so you have
M1 + d1(C-M1) = M2 - d2(C-M2)

Answer 11

where M1 and d1 are one of the combinations of percent to pay and minimum, M2 and d2 are the other

Answer 12

if you want help making sense of that formula I can help

Answer 13

brb

Answer 14

back, this is a hard problem for many students, but it is doable and understanding the why more than just the answer will be very helpful in later problems

Answer 15

I think I am way more confused now!

Answer 16

don't worry, that equation looks WAY more confusing than it is

Answer 17

I'll fill it in with the numbers, then it will looks less intimidating

Answer 18

I figured. HAHA

Answer 19

thank you that might help

Answer 20

80 + 0.40*(C-80) = 210 + 0.30*(C-210)

Answer 21

so do I add 80+0.40 first and then 210+0.30 ?

Answer 22

not quite, that up there is just an algebraic equation, you need to solve for C

Answer 23

oh boy. LOL

Answer 24

I'll get rid of the parentheses,

80 + .40*C + 24.0 = 210 + .30C - 63

Answer 25

I have no clue where to start.

Answer 26

oh, dang it I screwed up a sign, rather
80 + .40*C - 24.0 = 210 + .30C - 63

Answer 27

Still have no clue

Answer 28

So just with the equation, move C to one side like this
80 + .40*C - 24.0 (- .40*C) = 210 + .30*C - 63 (- .40*C)
gives you
80 - 24 = 210 -.10*C-63

Answer 29

then move the rest of the equation to the other side (everything but the C)

80 - 24 + 63 - 210 = 210 - .10*C - 63 (+63 - 210)
-91 = -.10*C

Answer 30

ok I think I see that.
