conversations.value: Can you explain how to solve this math problem: In a certain country store, there are three kinds of bottled drinks. A cola, which costs $3, a juice for $1.5, and water for $1 per bottle. One day the store was able to sell 15 bottles of cola, 25 bottles of water, and 12 bottles of juice. How much did the shop earn?

conversations.value: 15 bottles of cola is a cost of 15 * 3 = $45.
  12 bottles of juice make up to 12 * 1.5 = $18.
  As each of the 25 sold water bottles was $1, the shop made a total of 45 + 18 + 25 = $88.
