conversations.value: Phil started his day with $40. He bought a slice of pizza for $2.75, a soda for $1.50 and a pair of jeans for $11.50.  If he has nothing but quarters left of his original money, how many quarters does he now have?
conversations.from: assistant
conversations.value: The total cost of pizza, soda and jeans is $2.75 + $1.50 + $11.50 = $15.75
  He now has $40 - $15.75 = $24.25 left.
  There are 4 quarters in $1.00 so $24 is equal to 24 x 4 = 96 quarters.
  25 cents is equal to 1 quarter.
  Therefore, Phil has 96 quarters + 1 quarter = 97 quarters now.
