conversations.value: Solve the math problem: Big Lots is having a sale. All chairs are 25% off. If you buy more than 5 chairs, you get an additional 1/3 off the discounted price of the number of chairs over 5. If you bought 8 chairs that were normally priced at $20, how much do the chairs cost in total?

conversations.value: You save $5 per chair with the 25% off sale.
  On sale chairs cost $15 each because 20 - 5 = 15
  You bought 3 chairs above the 5 required before the extra savings starts because 8 - 5 = 3
  You save an extra $5 on these chairs because 15 x (1/3) = 5
  The first five chairs cost $75 in total because 5 x 15 = 75
  The final three chairs cost $30 in total because 3 x 10 = 30
  In total they cost $105 because 75 + 30 = 105
