In this problem, Julie is the basis for figuring it out.

J = Julie's Weight

Ted = 2j
Mike = 3j

2j + 3j + j = 210 or 6j

210 ÷ 6 = 35

With this, we know Julie's weight. Also, that she might as well be skin and bones.

35 × 2 = 70

35 × 3 = 105

105 + 70 + 35 = 210

Julie's Weight = 35 lbs.
Ted's Weight = 70 lbs.
Mike's Weight = 105 lbs.
