The answer is 9
You divide 143 % 11 to get 13. 13 is the number they make an hour, so if you divide 117 % 13 you will get 9.

What kinda of math is this so i can answer..
:)
Let Mary Sue have m necklaces and Betty have b necklaces.
And they have 603 necklaces altogether, that is
m + b =603
And Mary Sue has 115 more necklaces than Betty, that is
m=b +115
Substituting this value in first equation we will get
b+115+b=603
Subtracting 115
2b= 488
b= 244
So Betty have 244 necklaces .
