Answer:
n=40
Explanation:
I am not sure why the equation is using 0.5n rather than 0.25n as 0.5n would mean 2 subscriptions. If you are solving for n then the answer is 40.
Steps:
First we need to single out n so we can find the value of n for the equation to equal 25.
20=0.5n Subtract 5 from both sides in order to get n by itself.
40=n Divide 20 by 0.5 to get the exact value of n.
If you are looking for the number of subscriptions sold then the value would be twice n as n is equal to two subscriptions.
