Samuel,Rick and daniel sshare $700. 4times samuels share is equal to 5 times ricks share. twice ricks share is also 3 times daniels share.how much does daniel

OK.....

2R=3D     or    R = 3/2D

4S=5R      (and in the step above R= 3/2D....substitute this value for R)

4S = 5 (3/2D)

S= 5/4 (3/2D) = 15/8 D

the total money   R + S + D = 700

Substitute for R and S      3/2 D + 15/8 D + D = 700     Solve for D = 160    ( then R= 240  and S=300)
