Ryan saved $55 more than Jim. Chris saved 6 times as much as Jim. Donna saved half as much as Chris. If the children saved $3245 altogether how much did each child save?

R = J + 55
C = 6 J
C = 2 D
R + J + C + D = 3245
Four equations; four unknowns.
J + 55 + J + 2D + D = 3245
2J + 3D = 3190
C/3 + (3/2) C = 3190
(11/6)C = 3190
C = 1740
J = 290
D = 870
R = 345
