Answer to Question #135048 in Algebra for Angela

Question

kate has$4 more than twice as much as much money joe does. Joe has $16 less than Marcia does. In all they have $220. How much money does Joe have

Answer 1

Let x be an amount of money that Joe has. Hence, Kate has (2x+4). Marcio has (x+16).

In all they have $220, so we got the equation:

x+2x+4+x+16=220

4x+20=220

4x=200

x=50

So Joe has $50.
