conversations.value: I'm completely lost with this math problem: Blake bought 4  lollipops and 6 packs of chocolate. If each lollipop costs $2 and a pack of chocolate costs the same as four lollipops, how much change will Blake get back if he gave the cashier 6 $10 bills?
  Can you give me a hand?

conversations.value: Four pieces of lollipop cost $2x 4 = $8
  A pack of chocolate costs $8 so 6 packs cost $8 x 6 = $48.
  The total amount that she needs to pay is $8+ $48= $56.
  Blake gave the cashier $10 x 6 = $60.
  So, her change is $60 - $56 = $4.
