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?
Thoughts? Step-by-step reasoning:
User
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.
Thus, the answer is 153.
