Q: 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?

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