Answer:

  • See below

Step-by-step explanation:

<u>DVDs</u>

  • d = 925 - 12t

<u>Blu-rays</u>

  • d = 507 + 26t

<u>Solve the system:</u>

  • 925 - 12t = 507 + 26t
  • 26t + 12t = 925 - 507
  • 38t = 418
  • t = 418/38
  • t = 11

<u>Number of disks sold in 11 months:</u>

  • 925 - 12*38 = 469

There will be 469 DVDs and Blu-Ray discs sold per month in 11 months
