Question 140906
Let amount A had be x, B had be 2x and C had be 3x.
Let s be the sum.
x+2x+3x=s
since we must divide C's money in fourths, lets multiply the equation by 4.
4x+8x+12x=4s
7x+17x=4s A gets 3x and B gets 9x of C's 12x
7x/4 + 17x/4 = s Divide each side by 4
17x/4 - 7x/4 = 2000
10x/4=2000
10x=8000
x=800
x+2x+3x=s
800+1600+2400=$4800.
