Question

adriano runs a website that helps writers write better stories every month he receives a subscription fee of $5 from each new subscribers to his website. the website had 200 subscribers last month this moth 40 new members joined the website and 10 cancelled there subscription. how much money will adriano's online business earn this month?

Answer 1

Last month number of subscribers: 200

This month:

40 new members

10 cancelled there subscription.

This moth the earn is equal to the fee payed for the new members. Because the 200 subscribers are part of the earns of the last month and the cancelled members pay the fee the last month (there is not a d for the members that cancel the subscription).

Then , the earns in this month are: $200

`40\cdot5=200`
