[tex]Rules\ of\ rounding\ a\ number; \\ \\ Round\ it\ up\ if\ x<5 \to 9 \\ Round\ it\ down\ if\ x>4 \to 1 \\ \\ x_{1}=182 \\ x_{2}=439 \\ x_{3}=217 \\ \\ Let\ x_{1}, x_{2}\ and\ x_{3}\ be\ a\ rounded\ number... \\ \\ x_{1}=182\to \boxed{200} \\ x_{2}=439\to \boxed{400} \\ x_{3}=217 \to \boxed{200} \\ \\ Formula; \\ x_{1}+x_{2}+x_{3} \\ \\ x_{1}+x_{2}+x_{3}\to \boxed{200+400+200} \\ \\ Thus,the\ answer\ is\ \boxed{B.200+400+200}. \\ \\ Hope\ it\ Helps:) \\ Domini [/tex]
