\(XC = 30\) yards, \(BC = 80\) yards, and \(XY = 60\) yards
\(AC = AX + XC = AX + 30\)
Triangles AXY & ACB are similar triangles, so
\(\frac{AX}{XY} = \frac{AC}{BC}\)
\(\frac{AX}{60} = \frac{AX+30}{80}\)
\(AX = 90\)
Qt A > Qt B

AC=AX+XC=AX+30
BC/XY=80/60=AC/AX
4/3=AC/AX, 4AX=3AC ---> PLUG INTO AC=AX+30 OR 4AC=4AX+120 ---> 4AC=3AC+120, AC=120
AX=120-30=90
Quantity A: 90
Quantity B: 80
Quantity A>Quantity B and answer is A
