Question

2) Jamie has twice as much money as Kristen. Together they have $36. How much money does each have?

Answer 1

Answer:

jamie has 24 and kristen is 12

Step-by-step explanation:

jamie is twice  kristan which is 12+12

then 12 puls 24 is 36

Answer 2

For this case we have to:

Let x be the variable that represents the amount of money Jamie has.

Let y the variable that represents the amount of money that Kristen has

We have to:

$x = 2y\\x + y = 36$

We substitute the first equation in the second:

$2y + y = 36\\3y = 36\\y = \frac {36} {3}\\y = 12$

Looking for the value of x:

$x = 2y\\x = 2 (12)\\x = 24$

Answer:

So, Jaime has $ 24 and Kristen has $ 12.
