conversations.value: Find the answer to the math problem: At the new store, there are 3 times as many grape candies as cherry candies, and 2 times as many apple candies as grape candies. All the candies cost $2.50 each. If the total cost of the candies is $200, how many grape candies does the store have?

conversations.value: Total number of candies is 200/2.5=80 candies.
  Let x be the number of cherry candies.
  There are 3*x grape candies.
  There are 2*3*x=6*x apple candies.
  x+3*x+6*x=80
  10*x=80
  x=8
  There are 8*3=24 grape candies.
