Step-by-step explanation:
Let Andrew wage be = X
Cammi earns $20 more than Andrew So Cammi earns = 20 + X
Brenda earns $30 less than twice Andrew's wage
So she earns = 2X - 30
Their total combanied wage is $400
So Andrew + Cammi + Brenda = $400
X + 20+X + 2X-30 =400
4X - 10 =400
4X=400+10
4X=410
X= $102.5
So Andrew earns $102.5
Cammi earns $122.5
Brenda earns $175
