Chip and Arlene have 60 shares of stock between the two of them. If you double the number Arlene has and halve the number Chip has, then they would have the same number of shares. How many shares does Arlene have?

hmmm

AAAaannndd the bot gets it wrong yet again!

and yoo is wrong as well.

c+a = 60
2a = c/2
2a = (60-a)/2
2a = 30 - a/2
5/2 a = 30
a = 12
so arlene has 12 and chip has 48
check: 2*12 = 24 = 48/2

To find out how many shares Arlene has, we can start by assigning variables to the unknowns. Let's call the number of shares Arlene has "A" and the number of shares Chip has "C".

We know that Chip and Arlene have a total of 60 shares, so we can write the equation:
A + C = 60

We also know that if we double the number of shares Arlene has (2A) and halve the number of shares Chip has (0.5C), they would have the same number of shares. This can be written as:
2A = 0.5C

To solve these two equations, we can use substitution or elimination. Here, we'll use substitution by rearranging the second equation to solve for C:
2A = 0.5C
C = 2A / 0.5
C = 4A

Now, we can substitute this value of C into the first equation:
A + 4A = 60
5A = 60
A = 60 / 5
A = 12

Therefore, Arlene has 12 shares.
