The X variable is defied as the number of dimes collected.
Step-by-step explanation:
The X is next to 10 cents so therefor i can instantly infer that it is talking about the dimes. The question is asking how many dimes were collected so then that means that x would have to multiply the dimes to count how much money they raised. So we can now fully infer that the X variable is defied as the number of dimes collected.
