conversations.value: This math problem has got me stumped: Hannah bought a new washing machine for $100 and a dryer that costs $30 less. Hannah got a 10% discount for buying two appliances. How much did Hannah pay for the two appliances after the discount?
  Can you show me the way?

conversations.value: The dryer costs $100 - $30 = $70.
  So the washing machine and dryer cost $100 + $70 = $170.
  Hannah got $170 x 10/100 = $17 discount.
  Thus, Hannah paid $170 - $17 = $153.
