Can somebody help me please??
yes maam
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)
imam little confused on how to do this this is accounting rite
system of equations
let a = the number of users who generate ad revenue, let s = the number of users who pay for a subscription. then how would we calculate the total earnings using these variables? how would we calculate the total number of users using these variables?
a+s?
@pgpilot326
a + s = ?
690
so that's the total number of users equation... a + s = 690. now, what about the total revenue equation?
a + s = 2064
no, how much revenue for each ad user? how much for each subscriber user?
remember, a + s = 690 so it can't be that a + s = 2064 also!
I'm not sure
they get $2 for every ad user and $11 for every subscriber user so 2a + 11s = 2064.
ahhh
now you have your 2 equations with 2 unknowns... your system. can you solve it from here?
a = 614 s= 76? not 100% sure
well 614 + 76 = 690 so that works there... 2(614) + 11(76) = 1228 + 836 = 2064, so look like you got it!!!
thank you
you're welcome!
