Lilly ran a barbie doll shop.
She bought dolls at $6 each from a wholesaler.
She sells each doll at $14.
A doll is given free if a customer buys 2 dolls.
Last week, her customers either bought 1 or 2 dolls.
As a result, she had to give away 120 barbie dolls.
If her total earnings last week was $2000, how many customers bought only 1 doll each?
