conversations.value: I'm completely lost with this math problem: Vivi bought fabric to make new pillows for her bed. She spent $75 on checkered fabric and $45 on plain fabric. If both fabrics cost $7.50 per yard, how many total yards of fabric did she buy?
  Can you give me a hand?

conversations.value: The total yards of the checkered fabric is $75 / 7.50 = 10.
  The total yards of the plain fabric is 45 / 7.50 = 6.
  So, Vivi bought a total of 10 + 6 = 16 yards of fabric.
