Maria, hans, and dan have a total of $95 in their wallets. dan has 3 times what hans has. hans has $10 more than maria. how much do they have in their wallets?

It looks like everyone's amount of money is based on Maria's amount of money.  Let's say Maria is M, Hans is H and Dan is D.  Maria has M amount of money.  If Hans has 10 more than Maria, he has M+10.  If Dan has 3 times what Hans has and Hans has (M+10), then Dan has 3(M+10) which is 3M+30.  Altogether they have 95 dollars.  So we will add up what they have and set it equal to 95.  M+10+M+30+3M=95.  That simplifies to 5M+40=95 and 5M=55.  Therefore, Maria has 11 dollars.  Hans has 10+11=21, and Dan has 3(21)=63.  11+21+63=95
