Question 1151840: A website advertises properties for sale. 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. Answer by ikleyn(52810) (Show Source):
Let y = the number of advertisements that resulted in a sale of the property.
Then 49-y is the number of advertising that did not result in a sale of the property.
Your equation to find y is this revenue equation
140*y - 30*(49-y) = 3120.
From the equation,
y = = 27. ANSWER
