Solution 1
Use logic to solve this problem. You don't actually need to use any equations.
Neither Jo nor Bo has as much money as Flo. So Flo clearly does not have the least amount of money. Rule out Flo.
Both Bo and Coe have more than Moe. Rule out Bo and Coe; they clearly do not have the least amount of money.
Jo has more than Moe. Rule out Jo.
The only person who has not been ruled out is Moe. So is the answer.
