Answer: 15
Step-by-step explanation:
Given: In First video streaming service:
membership fee = $15
Per movie cost = $1.25
In Second video streaming service:
membership fee = $0
Per movie cost = $2.25
Let x be the number of movies for which services cost you the same amount.
Total cost for first = 15+1.25x
Total cost for second = 0+2.25x= 2.25x
as per given,
15+1.25x = 2.25 x
⇒ 2.25 x - 1.25x = 15
⇒ x=15
So 15 movies must be streamed from servies to cost you the same amount.
