<human>:  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?
<bot>: How many yards of checkered fabric did Vivi buy? ** The total yards of the checkered fabric is $75 / 7.50 = <<75/7.50=10>>10.
How many yards of plain fabric did Vivi buy? ** The total yards of the plain fabric is 45 / 7.50 = <<45/7.50=6>>6.
How many yards of fabric did Vivi buy? ** So, Vivi bought a total of 10 + 6 = <<10+6=16>>16 yards of fabric.
