Give the step-by-step reasoning process and then the final answer. 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?
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.
The final answer: 16.
