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

### Instruction:
A carton of ice cream contains 10 scoops each.  Mary has 3 cartons of ice cream, one chocolate, one strawberry and one vanilla.  Ethan wants one scoop of vanilla and one of chocolate.  Lucas, Danny and Connor all want 2 scoops of chocolate.  Olivia would like a scoop of vanilla and one of strawberry.  Shannon wants twice as much as Olivia.  How many scoops of ice cream will be left?

### Response:
Let's start with the chocolate.  3 cartons * 10 scoops/carton = 30 scoops of chocolate.  Then, we have to subtract the number of scoops of chocolate that will be eaten.  Lucas, Danny and Connor are going to eat 2 scoops each, so that's 6 scoops.  Ethan is going to eat one scoop, so that's 7 scoops.  That means we have 30 - 7 = <<30-7=23>>23 scoops of chocolate left.
Now let's look at the vanilla.  3 cartons * 10 scoops/carton = 30 scoops of vanilla.  Ethan and Olivia will each eat one scoop of vanilla, so that's 2 scoops.  Shannon will eat twice as much as Olivia, so that's 4 scoops.  So we have 30 - 2 - 4 = <<30-2-4=24>>24 scoops of vanilla left.
Finally, let's look at the strawberry.  3 cartons * 10 scoops/carton = 30 scoops of strawberry.  Olivia will eat one scoop, and Shannon will eat twice as much as Olivia, so that's 3 scoops.  So,
