Answer:
Step-by-step explanation:
Itunes : 0.99 per song......let d represent the number of songs
so the expression for this is : 0.99d
Napster : 10 bucks + 0.89 per song
this expression would be : 10 + 0.89d
so if u want to find out when they will be the same, set them equal to each other and solve for d
0.99d = 10 + 0.89d
0.99d - 0.89d = 10
0.10d = 10
d = 10 / 0.10
d = 100.......so 100 songs must be purchased <===
check it...
itunes : napster :
0.99(100) = $ 99 10 + 0.89(100) = 10 + 89 = $ 99
it checks out :)

Answer:
Option C
-5, -2, 1, 3
Step-by-step explanation:
to get the list that orders the numbers from the least to the greatest, we need to, first of all, know the smallest and the largest numbers.
The largest number is easy to guess - it is undoubtedly 3.
However, the smallest number may be a bit tricky because we are dealing with negative numbers. When dealing with negative numbers, the numbers with greater magnitudes are actually smaller. This means that -5 is less than -3, which is less than -2, and so on.
Coming back to our question, we can now order the numbers as -5, -2, 1, 3 which is option C
