Answer 6

This is a system of equation...we just need to solve for the variables

Lets songs = s
and
videos = v

So

\[\large 5s + 7v = 295\]
\[\large 10s + 3v = 150\]

solve for 's' and 'v'

Answer 7

Well actually...just solve for 's' since we only care about the songs

Answer 8

s=3
v=40

Answer 10

Perfect, now what does that tell you?

It tells us that each song downloaded costs 3 points and each video costs 40 points

Good!

Now...we know she has a total of 999 points

So if each song cost 3 points...and she has 999 points to use....then yes you are correct as she can download 333 songs at max

Answer 11

Thank u!
