question: Ellen and her sister, Lani, went to the mall to buy presents for their mom. Ellen bought a pair of leggings for $100 and a photo frame for $5. Lani bought a pair of sunglasses at $30 and two bathrobes at $100 each. How much did they spend in all?
answer: Ellen spent $100 + $5 = $<<100+5=105>>105.
  Two bathrobes cost 2 x $100 = $<<2*100=200>>200.
  So, Lani spent $30 +$200 =$<<30+200=230>>230.
  Therefore, they spent $105 + $230 = $<<105+230=335>>335 in all.
