Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website. Last month, the website had 100 subscribers. This month, 30 new members joined the website, and 10 members cancelled their subscription.
How much money will Kiersten’s online business earn this month?

Respuesta :

200 dollars for this month. overall 1200.
I believe the answer would be $1200. Giving she makes $10 from every subscriber she has then last month she would have had $1000. Since she gained 30 subscribers, that would rise to 130 subscribers but since she lost 10 which would bring it back down to 120 subscribers. 

Therefore, your answer is 120 x 10 = $1200.
