If the property is sold within the month, the website charges $140 for the advertisement, but if the property is not sold within the month, the website pays the advertiser $30. In a particular month, 49 advertisements were placed, and a total of $3120 was made across all advertising. Solve for y, the number of advertisements that resulted in a sale of the property. \n" ); document.write( "
