**PsyDAG**, Sunday, October 25, 2009 at 11:36amY = Z + 14 and

7Y = 5Z

Substitute Z + 14 for Y in the second equation and solve for Z. Go to the first equation to get Y. After that, it should be no problem to find X.

I hope this helps. Thanks for asking.

X Y Z

10 7 5

FRPM LAST TWO RATIOS:

5Y=7Z

FROM EQUATION (i)

5(Z+14)=7Z

Z=$35

NOW PUTTING Z=35 IN (i)

Y=35+14

Y=$49

NOW FROM FIRST TWO RATIOS

7A=10B

7A=10*49

A=$70

TOTAL MONEY= $70+$49+$35=$154
