Data Sufficiency (DS) | Re: To raise funds, a racing team sold T-shirts imprinted with

Thank youmikemcgarry for your explanation. I understand 100% with your explanation.

However, this is the reason why I think that n=1.

In addition to the $100 setup fee, the team paid $7 foreach T-shirt.

Whatever the n shirts they buy, but if the team paid $7 for EACH means n=1right?

I buy 100 iPhone and I should pay 1.000 USD each.

This is one that makes me confused.
