Answer:

Option A

Step-by-step explanation:

Let's denote:

x is the number of albums Teresa downloads.

y is the number of individual songs Teresa downloads.

=> 9x + y = 25

Let's check:

Option A: x = 2 and y = 7 => 9 x (2) + 7 = 18 + 7 = 25 => valid

Option B: x = 1 and y = 8 => 9 x (1) + 8 = 9 + 8 = 17 => invalid

Option C: x = 4 and y = 5 => 9 x (4) + 5 = 36 + 5 = 41 => invalid

Option D: x = 3 and y = 6 => 9 x (3) + 6 = 27 + 6 = 33 => invalid
