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 = <T>divide(75, 7.5)=10.0
The total yards of the plain fabric is 45 / 7.50 = <T>divide(45, 7.5)=6.0
So, Vivi bought a total of 10 + 6 = <T>add(10, 6)=16 yards of fabric.
