Question

Ad revenue for a web service is about $2 a month per each free user. A monthly “premium” subscription costs $11 dollars for the month, but does not make any ad revenue. The first month showed that 690 users used the web service that month earning a total of $2,064 between ad revenue and subscriptions.

Determine the system of equations describing this relationship.

Calculate the number of users of each type(free users,subscribers)

Answer 1

Anybody got any idea?

Answer 2

i might :P

Answer 3

:DD

Answer 4

let there be 'f' free users and 'p' premium users
total users = f+p

given: total users for first month = 690

so we have : f + p = 690
=> p = 690 - f

revenue 1 free user = $2
revenue by 'f' free users = $2*f

revenue by 1 premium user = $11
revenue by 'p' premium user = $11*p

total revenue = (2*f) + (11*p) = $2064

=> 2f + 11(690-f) = 2064

solve for f. then use it to get the value of p.
