Carmen, Reuben, and Bob have a total of $133 in their wallets. Bob has 3 times what Reuben has. Carmen has $8 more than Reuben. How much does each have?
So you will want to form a few equations. The first one is: C+R+B=133 Then you will want to form an equation for Bob: B=3R Then, another for Carmen C=R+8
Knowing this information, you can plug each in, solving for R.
R+8+R+3R=133 Now Solve 5R+8=133 Subtract 8 from both sides 5R=125 Divide 5 from both sides R=25 Now substitute R in for Carmen and Bob equations.
R=25 Reuben has $25 C=8+25 Add C=33 Carmen has $33 B=3(25) Multiply B=75 Bob has $75
