Answer:
$1,200
Step-by-step explanation:
We know that Kiersten already has 100 subscribers. This month 30 new members joined, so her website would have 130 subscribers, however 10 members canceled their subscription. So if she went up to 130 subscribers, but 10 quit, we just do 130-10= 120. So we know she currently has 120 subscribers to her website.
We also know that from each member, Kiersten receives $10
So we can set up an equation like this
(Number of subscribers) x (Subscription fee) = (Amount of money she receives)
So now lets just insert the numbers into that
120 x $10 = $1,200
So Kirsten will make $1,200 dollars this month.
