Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
Total number of candies is 200/2.5 = <<200/2.5=80>>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 = 10*x = 80
x = 8
There are 8*3 = <<8*3=24>>24 grape candies.
