Answer:
B
Step-by-step explanation:
A] You download 2 songs.
B] You download 2 movies.
C] You download 1 song and 1 movie.
D] You don't have enough money for 2 downloads.
x= number of movies downloaded
g(x) = total cost in dollars.
From g(x)=x
There is a slope of 1
That is, the movies cost $1 per movie.
It is a proportional relationship because of the absence of y-intercept
f(x) has a slope of (1/2) and y-intercept $2
f(x) = (1/2)x + 2 is the function for the cost of downloading music.
When we get to 3 downloads,
f(3)=g(3) and above, music downloads will be cheaper because they only cost 1/2 dollar for each additional movie compared to $1 for each movie.
For 2 movie downloads
we have,
f(2)=3
g(2)=2
So, downloading two movies will be cheaper.
One of each costs $1 + $2.50,
more than either of the other choices.
