Can someone help me figure out what the dependent variable in this problem is supposed to be?

"I asked you to imagine that I worked for a record company and that my boss was interested in predicting record sales from advertising. Before a record is released, the executive notes the amount spent on advertising, the number of times the record is played on the radio the week before release, and the attractiveness of the band. He does this for 200 different records (each made by a different band). Attractiveness was measured by asking a random sample of the target audience to rate the attractiveness of each band on a scale from 0 (hideous potato-heads) to 10 (gorgeous sex objects). The mode attractiveness given by the sample was used in the regression (because he was interested in what the majority of people thought, rather than the average of people's opinions)."

Thank you !
