[tex]Let\ x\ be\ the\ money\ of\ Ronnie \\ Let\ x+250-100\ be\ the\ money\ of\ Cindy \\ Let\ 250\ be\ the\ money\ of\ Carla.[/tex]


[tex]Equation;x+250-100+x+250=900 \\ \\ 2x+400=900 \\ \\ 2x=900 \\ \\ \frac{2x}{2}=\frac{500}{2} \\ \\ \boxed{x=250} \\ \\ .Conclusion; \\ Thus,Ronnie's\ money\ is\ \underline{Php\ 250}[/tex]

[tex]Checking; \\ where\ x\to250 \\ \\ (250+250-100^{\underline{Cindy}})+250^{\underline{Carla}}+250^{\underline{Ronnie}}=Php\ 900 \\ \\ 400+250+250=Php\ 900 \\ \\ \boxed{Php\ 900=Php\ 900}\ \underline{TRUE} \\ \\ Hope\ ity\ Helps:) \\ Domini[/tex]
