**Reiny**, Sunday, October 21, 2012 at 10:35pmoriginal amount of Rosa and Marty --- x

after spending:

Rosa --- x-45

Marty --- x-117

now Rosa has 4 times as much as Marty

x-45 = 4(x-117)

x-45 = 4x - 468

-3x = -423

x =141

They both had 141

check: after spending:

Rosa had 141-45 = 96

marty had 141-117 = 24

Does Rosa have 4 times as much as Marty ??? YES!!
