conversations.value: I'm completely lost with this math problem: Chad is hosting a BBQ on the hottest day of the year, where there will be a total of 15 people.  He will need 2 pounds of ice per person to account for the heat.  One pound bags of ice are sold for $3.00 for a pack of 10.  How much will he spend on ice?
  Can you give me a hand?

conversations.value: He’s inviting 15 guests and will need 2 pounds per person so he will need 15*2 = 30 pounds of ice
  Ice is sold in 10-pound bags and he needs 30 pounds so he will need 30/10 = 3 bags of ice
  Each bag is $3.00 and he needs 3 bags so they will cost 3*3 = $9.00
