let b be the number of bracelets she had before she sold any.
She sold 23 bracelets, therefore the number she has left is
b - 23
- and this is equal to 112.

i think it is D
OpenStudy (welshfella):
I think you are guessing
after 23 have been sold the number left is b take away 23 or b - 23.
- and we are also told in the question that this number left is 112.
so these 2 things are equal
so
b - 23 = what?
OpenStudy (123ab456c):
A
OpenStudy (123ab456c):
IS IT A

Sorry I missed your earlier post
The answer is D
b - 23 = 112
now add 23 to both sides
b - 23 + 23 = 112 + 23
b = 135
OpenStudy (123ab456c):
its fine thanks for the help i told you the answer was D though
