conversations.value: Ernie's income is 4/5 of what it used to be and Jack's income is now twice what Ernie used to make. How much do they earn combined if Ernie used to make $6000?

conversations.value: If Ernie's income is 4/5 of what it used to be, she is earning 4/5*$6000=$4800 now
  Jack's income is now twice what Ernie used to make a total of 2*$6000 = $12000
  Combined, Ernie and Jack are making $12000+$4800 = $16800
