How much does the dryer cost? ** The dryer costs $100 - $30 = $<<100-30=70>>70.
How much do the washing machine and dryer cost together? ** So the washing machine and dryer cost $100 + $70 = $<<100+70=170>>170.
How much did Hannah get as a discount? ** Hannah got $170 x 10/100 = $<<170*10/100=17>>17 discount.
How much did Hannah pay for the two appliances after the discount? ** Thus, Hannah paid $170 - $17 = $<<170-17=153>>153.
