Sammyjo said:Thank you, Jennifer, for your clarification of this problem. I initially thought that the answer was 17, but I was not certain of it, so I asked my daughter her opinion. I will continue to seek her counsel. My daughter and I are only human and sometimes we make mistakes. So, I will change my answer back to 17. Thanks!
