conversations.value: Jackie's favorite cosmetic company was offering free shipping when you spent $50.00.  Jackie ordered her favorite shampoo and conditioner that each cost $10.00 a bottle and 3 bottles of lotion that cost $6.00 each.  How much more money does Jackie need to spend to be eligible for free shipping?
  Give me a solution to this problem

conversations.value: The shampoo and conditioner cost $10 each so 2*$10 = $20.00
  3 bottles of lotion cost $6.00 each so 3*$6 = $18.00
  So far she has spent $20+$18 = $38.00
  You need to spend $50.00 for free shipping and she has spent $38.00 already so she needs to buy $50-$38 = $12.00 more in products
