conversations.value: A liter of chlorine costs $10 and is now sold at 20% off. A box of soap that costs $16 is now sold at 25% off. How much will you save if you buy 3 liters of chlorine and 5 boxes of soap?
  How to solve this?

conversations.value: For each liter of chlorine, I can save $10 x .20 = $2.
  For each box of soap, I can save $16 x .25 = $4.
  With the 3 liters of chlorine, I can save $2 x 3 = $6.
  With the 5 boxes of soap, I can save $4 x 5 = $20.
  Therefore, I can save a total of $6 + $20 = $26.
