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
Last month, Kiersten earned $1000 (wow that's a lot of money :3) and this month, she earned $1200.
Answer:
Last month's income: $1000
This month's income = $1200
Step-by-step explanation:
Number of subscribers for last month = 100
Fee per subscriber = $10
Sol, last month's income = 100(10) = 1000
This month, 30 new members joined and 10 of the existing members cancelled their subscription.
So, number of subscribers this month = 100 + 30 - 10 = 120
This month's income = 120(10) = 1200
