Let ( x ) be the cost of dosin table. And ( y ) be the cost of chaist Oby the given information, we ( g^{circ} t ) [ 1 cdot 1 x+1 cdot 25 y=1050 ] [ 1.25 x+1.1 y=1065 ] Solving ( Leftrightarrow B ) (2)( quad ) we get ( (0 times 1.25) Rightarrow 1.375 times+1.5625 y=1312.5 ) ( (2 times 1 cdot 1) Rightarrow 1 cdot 3+5 times+1,2100 y=1111 cdot 5 ) ( 0-(2) ) ( 0+0 cdot 3525 y=141 ) [ left{begin{array}{l} y=frac{141}{0.3525}=400 end{array}right. ] (1) ( Rightarrow 1-1 x+1 cdot 25(400)=1050 ) ( Rightarrow quad 1 cdot 1 x=1050-500 ) ( Rightarrow quad 1, x=550 ) [ x=frac{550}{1-1}=500 ] Gost sf ( f a b l e, x=500 ) Eost of Chain ( , y=400 )
