conversations.value: Valerie earns $5000 per month, 1/2 of what her brother earns. If their mother earns twice their combined salary, what's the total amount of money they all have together?

conversations.value: Valerie's brother earns 2 * $5000 = $10000
  Their combined salary is $5000+$10000 = $15000
  Their mother earn twice their combined earnings, which is 2*$15000 = $30000
  The total amount of money they all have is $15000+$30000 = $45000
