Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money? Let's be accurate as possible.

Jethro has 60 / 3 = $20. Twice of what Jethro has is $20 x 2 = $40. Carmen has $40 - 7 = $33. The sum of all their money is $60 + $20 + $33 = $113.
The answer: 113.
