Answer: 55 brushes.
Step-by-step explanation:
Let x represents the number of art brushes Monique has.
Then, Number of brushes Chelsea has = 11x .
If they have 60 art brushes altogether, the we have the following equation :-
[tex]x+11x=60\\\\\Rightarrow\ 12x=60[/tex]
Divide both sides by 12 , we get
[tex]x=5[/tex]
Then, Number of brushes Monique has = 5
Number of brushes Chelsea has = 11(5)=55
