Question

SHould Be VERY easy :)?

Please help. confused

Carmen had $10 more than 3 times as much money as Kathy. After giving Kathy $20, Carmen's amount is exactly twice Kathy's. How much did each girl begin with?

Answer 1

C = 3K + 10

C - 20 = 2(K + 20)

3K + 10 - 20 = 2(K + 20)

3K = 2(K + 20) + 10

3K = 2K + 50

1K = 50

Kathy started with K = $50

Carmen started with (3K + 10) = $160  

Answer 2

Carmen began with 160

Kathey with 50

160-10=150/3=50+20=70x2=140

Answer 3

I'm not super good with math but here goes.  Kathy started with 50 and Carmen started with 160.  This is illustrated by two equations.  Sorry for the mistake earlier

C = 3K + 10.

2K = C - 20.

3K + 10 - 20 = 2(K + 20).

3K -10 = 2K + 40.

K = 50

K = 50.  Kathy has 50 dollars.

Carmen had 10 + 3*50 which is 160

Answer 4

Do your own homework >:( lol j/k But whats with the ? do we look like 12 year olds?

Answer 5

C = 3(K) + 10

C - 20 = 2(K)

3K + 10 - 20 = 2K

K = $10

C = $40

Answer 6

Start by saying that Kathy had x.

How much did Carmen have? She had 10 more than 3 times x, which is 10 + 3x.

SHe then gave Kathy 20. How much did she now have?

How much did Kathy have. And we know that the amount Carmen had was twice what Kathy had.

See can you work it out from that.

Answer 7

(10 + 3k) - 20 = 2(k + 20) where c is carmen and k is kathy

3k - 10 = 2k +40

k = 50

c = 10 + 3(50)

160 - 20 = 2(50 + 20)

so, carmen started with 160 and kathy with 50

Answer 8

I think carmen had 70.00 and gave kathy 20.00 each girl began with 25.00

Hope this helped

carmen

20

20

20= 60.00 + 10.00 more= 70.00-20.00 given to kathy leaves 50.00

2/50=25.00

Answer 9

C = 10 + 3 K

C - 20 = 2 (K + 20)

therefore C = 2 K + 60 = 10 + 3 K

Subtract 2 K + 10

50 = K

Therefore C = 160

Answer 10

Amount Carmen had should be X and Kathy had can be Y

So if Carmen had $10 more than 3 times as much money as Kathy.

the equation is X = 3Y + 10

After giving Kathy $20, Carmen's amount is exactly twice Kathy's, the equation is X - 20 = 2Y

ie. X  = 2Y + 20

2Y + 20 = 3Y + 10

Y = 10

if Y = 10 then X = 40

Answer 11

If it's so easy, you can do it yourself.

Answer 12

C = 3K + 10

C - 20 = 2(K+20)

so C = 2K +60

so 3K +10 = 2K +60

so K =50

C = 160

so originally, Carmen had $160, Kathy had $50

Answer 13

let kathy be x

carmen = 3x+10

after giving

3x+10-20=2(x+20)

3x-10=2x+40

x=50

kathy = 50

carmen=160
